Top Ten Hardest Vocaloid Songs to Sing

There are very many Vocaloid songs to choose from; but it's not really how fast it is, it's how blurry it sounds when you sing it!

The Top Ten Hardest Vocaloid Songs to Sing

1 Dissapearance of Hatsune Miku - Hatsune Miku

It's easy to sing and really nice song except the fast and hard to breath part TwT

I agree that The Disappearance of Hatsune Miku is very hard to sing. I've studied and tried to sing this as much as I can, but it's just so fast paced! I'm going to try and learn it though because it is doable. I've seen someone sing it--one in English! So yeah, this song is very difficult in my opinion.

Fast and hard to catch. but I like listening to this song even I cannot understand

It is very fast and hard to understand but still can be easy to get used to and an amazing song.

2 Hatsune Miku's head exercises - Hatsune Miku

So I'm going to do this differently. I'm going to state some things you'll need to do before singing this song:
Shake your head like you never did before for 5 minutes straight while singing REALLY fast.
Duplicate yourself.
Have your duplicate turn invisible and talk about Sherlock Holmes having laser eyes.
Don't use vibrato.
Memorize a five minute long pop song in Japanese. - Tiptron

Well, nobody said you need to shake your head, since I'm sure people don't delete themselves while singing Disappearance, but it's hard enough regardless.

This song gives my neck pains for FIVE days straight. Why? Try sing this FAST song while shaking your head. Let's see if you could pass..

3 Worlds end dancehall and Two faced lovers - Hatsune Miku

The reason that these songs aren't #1 hardest, is because they have a rhythm, It's like rapping, but Japanese. Also, both of those songs are really fast, and equally rhythmic, so they are tied for #3. - Tiptron

I have World's End Dancehall down mostly, but it still leaves me out of breath at the very end. But Two Faced Lovers is just impossible for me. I can even do the dance for it that's in Googoo88's video of Two Faced Lovers... But I can't sing it for my life. I always get about 75% done, then start trembling like a leaf and have to stop.

I can sing most of World's end Dancehall, just that fast part needs practice. Two Faced Lovers I can sing all of it, I just need to memorize the second chorus at the end. - JamieG11

I'm trying to learn Two faced lovers and so far I have a few lines memorized! It can be hard to keep up the fast pace for so long, but luckily I can sing rapidly :D yay

4 Let's Say the P Names

I think this is a little bit harder than Dissapearence Of Hatsune Miku - OrangeRin

This definitely should be first, go look up. This is way harder than Sadistic Factory and than Disappearance of Hatsune Miku

I can sing like...maybe 80% of it, but even then it's difficult to sing because there's no breathing time in the song.

Definitely the fastest Vocaloid song out there, and one of my favorites.

5 Meteor - Hatsune Miku

The song is so soft... And that makes it hard for me because my voice is more loud when singing. I can easily sing the lyrics, sure. It's very slow and there lots of instrumentals parts, especially compared to the amount of time Miku is actually singing. But my voice can simply not reach the pitch Miku's can. Even so, number 5 is way too high for this song.

The long notes may be hard but I honestly don't get why "Meteor" is so high on this list. Miku's singing in this song is very soft and most of the eight minutes is instrumental.

Why this song is impossible:
1: Miku holds some of her notes for a REALLY long time.
2: The song is eight minutes long. - Tiptron

I'd have to disagree on the second part. It may be eight minutes long, but keep in mind that the singing is considered inferior to the instrumentals. There's more music than voice.

This song is easy I sung paradichlorobenzene f 2nd speed
They patched it to be faster much faster and I did it perfectly
I did like I love you no challenge
I even did 2D Dream Fever
Secret police English version
And the wuss song...

Can't Stop Me

6 P Mei Ittemiro! - Maretu

I hadn't heard this song before I found this list, and I gotta say - this deserves first. But I think maybe Disappearance has first because its more well-known?

Um this is obviously the hardest one. its just impossible

This song was not meant to be sung by mere mortals

...How is this not first?

7 Meltdown - Rin Kagamine

There is only some high pitched parts I think its not that hard - OrangeRin

I don't really understand, but I know that everyone has an opinion. I'm very young and can sing this lol...

Yes, "Meltdown" has understandable placing on this list! While the lyrics are easy to remember, Rin's insanely high pitched voice singing sharp notes? Yeah, no. As many other altos can probably relate, I don't think I could sing this on key even if I practiced my hardest.

I literally sound like a dying chipmunk on the high notes. It's impossible for me to come close to sounding like that, I can't even hum this song without sounding like I'm dying. Rin's voice is so sharp and difficult to mimic in any way.

8 Luvoratorrrrry! - Rin

This song is very easy to memorise and to sing.

Its not fast at all its just the pronunciations for RIN KAGAMINE but GUMI MEGPOID is easy t understand


It's so hard, the song is super fast._.

9 I like you, I love you - Rin Kagamine

I sang this to my crush (he understands some Japanese) and he asked me out. I learned each and every syllable. This was my favourite song for some time.

The beginning and chorus aren't that bad; what's really challenging. When she starts to stutter, it's hard to memorize each syllable, even if you speak Japanese because in the translation, all she's saying is "I, um, Sorta, Well, you know," - Tiptron

I completely disagree with this. The reason it SEEMS hard to sing is because let's face it, Rin's pronunciation in general is very unclear. If you want a hard Vocaloid song to sing, look up The Lost One's Weeping and Abstract Nonsense.

It's quite simple... Then the stuttering always throws me off. There's harder songs of Rin's out there, but in this song the vocals seemed hard to understand.

... You're kidding me right?

10 The Intense Singing of Hatsune Miku - Hatsune Miku

Sure the song is slow at first, but this song gets faster than The Disappearance of Hatsune Miku! That song is already un-singable from the speed of the song, if this is faster, shouldn't it be first?

Actually this is pretty harder than the disappearance of hatsune miku because I am not used to singing slowly because I am more used to singing dongs faster if your like me vote for this song even though at the end it's a bit easier because its faster.

This song goes from slow to fast. If that's not hard enough, it goes faster than "The Disappearance of Hatsune Miku," which is currently first on the list.

This song is as fast as "The Disappearance of Hatsune Miku" in the end how the hell isn't this on top 3?!

The Contenders

11 Sadistic - Music Factory

Seriously? This is lower than Disappearance?

Okay, I know it's not all too well known, but the singing isn't just fast, it's legitimately gibberish. At least you can catch the words with Disappearance of Hatsune Miku, but here you can't even figure out what she's saying at all.

I have to agree, this is the hardest in that list. I think I may add an other song, this song just deserves to be second before the one I'm going to put because it is inhuman.

This needs to be at least second. It's much harder than Disappearance of Hatsune Miku because that is doable - felispasta

No way in hell is this easier than The Disappearance Of Hatsune Miku. -.-

12 No Bousou - Kagamine Len

Kagamine Len no bousou is my death, I tried to sing it once and I was so out of breath and it's just impossible

This Song is way to fast to sing it, only one part in the refrain is actually singable

The title translated is the rampage of Kagamine Len. Of course it's gonna be hard.

As much as I love this song, Len needs to chill out.'

13 Ievan Polka - Hatsune Miku

Serious, guys? Hard or not, Ievan Polka is actually singable and there are a lot of Vocaloid songs which aren't. I mean that literally. Vocaloid does a lot of trills and stuff which is physically impossible for real people to sing unless they computerise their voices and this song is not one of them. Sorry, but I feel like I'm talking to a bunch of people who are completely new to Vocaloid.

Not be rude, but Ievan Polka isn't that hard to sing. Whether it's Finn or not I can sing it. All you really have to do is study the beat and lyrics of the song and you'll have it in no time! And trust me, I'm not very good at singing other languages but this song still isn't very hard. Sorry.

The tune is catchy enough to get it all in your head. BUT, it's very hard to memorize the lyrics if you don't speak Japanese because it's the same short chorus repeating itself for 4 minutes. That way, you have to memorize EVERY syllable and EXACTLY where each one goes. - Tiptron

The song is Finnish, not Japanese. Also, Miku completely botches the Finnish up, which makes it seem super unclear, when in reality, if you look up the real version of the song (IEVAN POLKA IS NOT MIKU'S SONG! IT'S A FOLK SONG DATING BACK HUNDREDS OF YEARS, WHICH WAS RECENTLY RECOVERED BY A FOLK BAND, WHICH SOMEONE MADE MIKU SING A COVER OF. ) it wouldn't be that difficult to sing.

It's not all that hard. But in the song the Finnish is, as another comment stated, all botched up. I'm not really used to singing in Finnish but it's very singable.

14 Francium - Hatsune Miku

How is this not 1st? I can easily sing all of the songs on thus list BUT this song!

This song is just a bunch of nonsense - Zero116

You breathe in the small instrumentals

Best song ever %100 - sorewachickenyo

15 Paradichlorobenzene

The reason I can not sing this song is because THE LONG WORDS THAT MY IDIOTIC SELF CAN NOT PRONOUNCE. It seems everyone know how to, and can sing these long words at a fast pace and make their voice all high pitched and all. And all you little kids who are bragging about singing this and questioning how I can not sing it... Well good for you, but you don't need to rub it in. You are a better singer than I am and you can hold your breath for a longer amount of time than me.

To answer the question of another comment 'Explain how this is easy for a 12 year old but hard for someone else.'

Not everyone can sing at the same level. Maybe you're way better at singing. Maybe you have practiced at this song a lot and I haven't. Whatever it is, you can sing it I can't. Age doesn't decide if you can sing better. I just started singing. I've never sang before in my life. You've probably sung before, even just for fun. I'm still adjusting my voice and finding the right paced songs for ...more

It can be difficult to sing if you don't know where to breathe. The note range is fine, the pace isn't too bad. But once you know where to breathe (or you can hold your breath for like, FOREVER) it's easy to sing

How is this hard? Explain how this is easy for a 12 year-old but hard for someone else.

So hard to say especially since nobody can pronounce paradichlorobenzene

16 The Lost One's Weeping - Kagamine Rin

Yeah, never trying this one at home when someone might question what I'm doing. Or I'll break my dog's ears...'enough said. - KobayashiMatcha21

I don't really have to scream the high notes (although they are still pretty high), but I still cannot do the Japanese! I can rock the English cover, but my voice starts to break sometimes if I sing it too much.

You need to be able to execute (scream) the high notes and do some major diaphragm exercises in your lower vocal range. It's also a quite fast-paced song, and Rin's unclear pronunciation makes it hard to sing along to, unless you want to find an utaite cover that's decent, which is hard, because again, this is a really hard song to sing! I don't see any reason why this is NOT hard to sing! Also, the lyrics are so sad and relatable that I find myself tearing up and choking, so that may play a major role as to why I sound like garbage.

No offense to anyone, but this song actually isn't that hard to sing. Trust me, I can't hit those high notes like Rin but it's still singable. If you really study the beat and lyrics of the song it gets easier to sing. Heck, I can even sing it in English now! Sorry, but this song isn't really that hard to master.

17 The Fox's Wedding - Hatsune Miku & Gumi

I can actually sing this song really well, but I practiced a lot. There aren't many breaks or pauses throughout the song to catch your breath and it's fast and sometimes a little high pitched for me, but it's not too bad.

Some of the parts are sorta easy to sing, but wow. It's a super fast song! Not to mention the whole series of the songs to go with it are just flat up messed up!

This song is literally hell. I mean, when do they take a breath in this one?! Also, the lyrics are just too suggestive. So, that's that...

I made a whole English translation and tried to sing it, only to find out I kept messing up the words and could pronounce anything right!

18 Daughter of White - Yowane Haku

Okay, I love this song. Haku's has an amazing voice, but I don't even remember how it goes! It's a very long song, so you would have to listen a lot to memorize the tune and lyrics. It would be time consuming. Maybe you won't be able to work or play if you spend all your time listening to one song and memorized it! - Tiptron

I really like this song but I can never comprehend the pronunciation

It's not really that hard to sing actually... it's pretty easy for me

Pretty simple but you just get bored easily being there singing for 8 minutes. - felispasta

19 Rolling Girl - Hatsune Miku

I learned how to sing this song in Japanese, and it only took me a week!

I can sing this as well, I never took singing lessons, and I'm also eleven. That probably sounds a bit coincidental, but I'm not kidding! It took 6 tries, and I lost my voice for an hour, but I sang it. Rolling Girl is a difficult one, though, so I can see this being at 19.

It's easy when you get the beat and rhythm, your Japanese doesn't need to be perfect if it's hard for you to pronounce (like me because of the accents I have) it's doable though. Keep tying hard!

Practice makes perfect! I can sing this song, but I've practiced SO much... But I don't even sound that good singing it still

20 A Tale of Six Trillion Years and Overnight - Ia

I'm not even gonna try lol

(says someone who somehow cried because of this sentiment is too much for pore ol' me.) - KobayashiMatcha21

Singable, but it takes quite some practice.

Pretty easy once you get the hang of it.

Have you even tried singing this

21 Invisible - Gumi and Rin Kagamine

I tried. I know it's not as fast as The Disappearance of Hatsune Miku or The Intense Singing of Hatusne Miku, but it's hard anyway. It starts fast, then you're half screaming, then you ARE screaming because those notes...I don't know, it might just be me, but it's hard.

The hard tempo, high pitched notes and quick lyrics all shape this song out to be a serious commitment in singing.

I really like this song

It's pretty fast, 204 bpm according to Project Mirai, Gumi's notes sound a bit husky, Rin's voice is very sharp and high, and the verses are just gibberish.

22 Two Faced Lovers

This... This song is just plain insane. It's too fast, you need to know which syllables not to pronounce if you want even a DECENT chance of singing it, and the verse is just insanely fast rapping.

Can we just remember how absolutely crazy fast this is?

Took me like a month and a half, but I can sing it - JamieG11

I tried this but dang

23 Nakakapagpabagabag - Len Kagamine

It's super high pitched, fast and has the word 'nakakapagapagabag', a word known to be difficult to say (even to people native to the language). It isn't in English or Japanese. It's also very robotic.

Lol I can say it (and spell it) though because I've watched it so many times. It's catchy!

Just read the title. Nakakapagpabagabag. It's an amazing song, but the tempo changes a lot.

I already sing this song since I'm a pilipino waah ( > o < ) /

Its easy for me, but when it comes to the game edit of this, its hard. The hard part is " mas sanay na akong nakalakad...". the nakalakad must be makalakad. I'll blame my saliva...

24 Matryoshka - Hatsune Miku and Gumi

I don't know about anyone else, but I think the notes for this song are INSANE. If you have a lower vocal range, it makes it ten times harder. It's very fast-paced in my opinion, and the fact that you have to say the odd words ( RIE) and switch from note to note constantly drives me crazy! Still Still love the song, can't sing it though

This was pretty easy for me... Compared to other songs like Meltdown and The Disappearance of Hatsune Miku, those are near IMPOSSIBLE.

I love this song! It took a bit to learn, I wouldn't say it was difficult, but it had its ups and downs whil I learned! I think why, is because I have a really high voice, so the high notes were easy. I was once called a chipmunk when I sang matryoshka, because of how high I went. I think I actually went higher than I was supposed to on accident, but it was a very fun song to learn!

I love how odd it is! It might be hard for some, but for me, that's the fun part of it. If you have a lower vocal range, there's probably a way to edit the music so it's lower. Did someone lower it for Akita Neru yet, since I've seen that many times before?

25 Butterfly on my/your right shoulder - Len Kagamine

For all the people who are saying they can sing this, sorry, but you can't. The actual tune is pretty easy and it's not too high, but it has a lot of trills only computers can do (like when it starts auto tuning and then when he/she makes this sound like a phone ringing and stuff). If you're talking about the actual tune and stuff, I totally get it, but all the computer-y affects are vital to the song because it's meant to sound like his voice is glitching. It's physically impossible to sing, but I don't want to call it "the hardest" because lots of other songs are like that, too. I really like it when Crypton adds this sort of thing. It sort of reminds you that the song is done by computers, then when there's none for a while, you start believing they're real again. That's how I see it, anyway.

This is an impossible song to sing because there is one part where they are singing with the words cut of and starting abruptly like a Vocaloid gone wrong. Also, it's hard to get this song stuck in your head without just getting the chorus, which is super catchy. - Tiptron

Am I the only once who can actually do the part where Len starts to glitch or whatever? It is a bit hard to change the words that quickly but it is possible, the rest of the song isn't that hard either. - niibo

I've got the chorus and some of the rest of the song down, but not the parts where it gets all auto tuned and stuff

26 Hatsune Miku's High Note Challenge - Hatsune Miku

This is the hardest song to sing. If you attempt this song, you may experience death to vocal chords.

I can sing this

You can die when you are trying to sing last parts XDD - OrangeRin

No living person can sing this song. It is way higher than meltdown.


27 Boku Boku Β

I find this extremely hard to sing without pausing, but I would place it at number 2. Honestly, I can only do half of the fast parts without having a pause and taking a short breath for half a second.

I think on Project DIVA PSP it was pretty much spamming buttons and you can’t see them either because you’re spamming all your buttons!

28 No Gekishou - Hatsune Miku
29 Now! - Rin-chan

This song is a challenge, even in English, especially when taking into account the relatively high pitched and repetitive chorus which is difficult to sing without quickly running out of breath that is, "Rin-chan now! Rin-chan! Rin-chan, Rin-chan, Rin-chan now! ". This song is like a tongue twister!

Rin-chan Now! Can be easy on the chorus but the rest is too fast and you can only sing if you know Japanese.

It's so bloody fast.

This is probably the easiest song in my opinion. I am 12 and my friends and I sing this perfectly fine.

30 Noushou Sakuretsu Girl - Hatsune Miku

This song is a really mindblown song. The lyrics are way too much, and if you're not Japanese I bet you'll spend a week to pronounce it well.
Also it's kinda rap song, but it's so fast-paced. Though, it's a great and popular song by rerulili.

31 Scarlet Rose - Lily

Scarlet Rose so low, really?

32 Warning of Impostors - IA

The chorus tempo is fast as hell its hard to sing..

33 Spinal Fluid Explosion Girl - Hatsune Miku and Gumi

High pitched and fast paced. I have trouble humming it!

34 +♂

I am shocked that "Plus Boy" is so low on this list. It honestly should have made it into at least the fifteen. Len's inhumanly fast singing, high pitched voice (Sorry Len) and the fact that the lyrics are written to sound like real dialogue (with plenty of eto's thrown in) are the main contributing factors in why I believed this piece should have scored way higher.

This is so low! It's really hard. - OrangeRin

I have to agree with that one!

It's too fast at some parts the first time you want to sing it, but it's ok after 2 or 3 try!

35 Dark Woods Circus

Rin's part is unbelievably high pitched. So are some of Miku's. Also, the part where the static noise cuts off one of the words always throws me off. This isn't as hard as some other songs higher up... But it's harder than you'd think, despite the slow pace of the overall song. Unless you have a super high pitched voice, this song will be a problem to sing for you.

Some of Miku's notes are hard to sing.

36 Kagerou Days

For this song you need some serious breath control, I mean, where can she even breath?! On my way to mastering this song though.

It's not impossible, but it needs A LOT of practice before it's mastered.

37 The Boy With No Eyes - Oliver
38 Secret Police - Hatsune Miku

The part where she says a ton of words in mere seconds is basically impossible.

The transitions into the chorus are hard and very fast but the chorus can be accomplished easily.

Miku sounds like she's on drugs.

I tried it and the fastest parts made it sound like I was speaking jibbrish but the rest was fine.

39 13 Year Old Killer - Kagamine Rin

First of all, you can't understand what she's saying most of the time. The second point, and the more important of the two would be THE RANGE. The first half or so would make you think "Hey, this song is so alto it doesn't even really feel like Rin." Then you get to the second half, and the soprano part is almost impossible. Whenever I even attempt it, my vocal chords hurt and all I sound like is half whistling, half indecipherable nonsense. Frankly, I'm a bit shocked nobody mentioned this song yet.

40 Tokyo Teddy Bear

Not really its easy you just need to have a low voice range

Actually this one is pretty easy

This is pretty easy to sing.

Come on, it is easy!

41 Cyber Thunder Cider - Vy1

This requires an intense amount of concentration to sing. It's doable, HOWEVER there are very few breathing breaks during the Cyber Thunder Cider section, and the Ah-Ah-Ah-Ah-Ah section is very hard. Still, it's an awesome song. - Winterush

Once you get the hang of singing cyber thunder cider at an odd rhythm, it's not too bad.

Reol can do it so can you.

42 Suji - Hatsune Miku

It's not the hardest but there are some pretty high notes and you have to say the syllables really fast. Even if you can hit the high notes it's mostly a kind of rap so you have to go from almost speaking to a pitch to singing high notes. It doesn't deserve to win but it certainly deserves to be on the list.

43 Suki Suki Suki

This should be In the top ten

44 PoPiPo - Hatsune Miku

The only reason this song is on here is because of the crazy PoPiPo-ing that only a Vocaloid can do! Don't get me wrong, I love this song; but you can try saying PoPiPo seven times and not pass out because of air lack. It's also really embarrassing to sing about vegetable juice at your school talent show. - Tiptron

I disagree. I can sing popipo very very easily personally. I can say popipo more than seven times and be fine, I have never thought of this as a difficult song to sing

Yeah, that popipo thing is close to impossible for most of us, but it's doable (I've done it before) and not as hard as some other songs, which actually are impossible.

This song is actually very easy. One of the first Vocaloid songs I learned.

45 Elsa-Maria - Mayu

Oh god this song is damn hard to sing... It's pretty fast and you barely get to breathe between sentences!

This song has really high pitches and allows almost nowhere for you to breathe.

46 The Fox's Wedding - Gumi and Miku

A really creepy but very interesting song, but the lyrics go by so fast and it's hard to keep up with the beat!

Come on, this should be higher than Meltdown, you got to be kidding.

The lyrics is so damn fast! I love it! I should maybe cover one day :D

47 Jitter Doll - Lily

The notes are hard to execute, and the voice just needs the PERFECT amount of emotion in it. It sounds quite dark, but the chorus requires you to just overflow with so many emotions (and get used to holding high notes) that it's nearly impossible, unless somehow you become a great voice actor overnight.

I (personally) can sing this song pretty well in both Japanese and English

48 Mozaik Role - Gumi

It's actually a rather easy song to sing in the name of Vocaloid. Minus the relatively high note in the chorus, it's got an average note range and isn't too fast. It's fun to sing.


49 I=nightmare - Seeu
50 Len - Kun Now! (Tei Sukone)

This is REALLY fast but not as fast as The Disappearance of Hatsune Miku, I'm surprised people forgot this one! (Different than Rin-Chan Now! )

I prefer this one over Rin-Chan Now!, but the question is, (prepare your ears for a 12-year old tantrum) HOW IS THIS HARD TO SING!? And anyway, I share opinions with Tei. Len-kun kawaii!
