My teacher: Time for a math session! Megalovania =?
Every student: The best boss theme ever!
My teacher: No, not quite.

I then grab a shotgun and shoot her like crazy.

How is this not first?! This was my favourite song of all songs for some time!

It's the end of the world, but... Hopes and dreams can save the world! - Delgia2k

Beautiful theme for staying determined.

Very heroic! And I Love Heroic Songs!

Both sad and happy and hopeful

This theme is extremely catchy and always gets stuck in my head. I love it to death and I think it deserves more love.

The song it's self isn't great,but the remixes it inspired I enjoy.in conclusion I voted this as my favorite

I love the calmness in this song

Love the repetition in the songs and it really fits to the boss omega Flowey!

It goes from total despair go absolute hope , and does so greatly the fact that the heavy part hits when flowey's defense reaches zéro and you star dping a lot of damage to a literal demi god juste mâles it perfect

So energetic and well synced to Muffet's animations, it's just the best.

This is just so energetic

My favorite, personally.

Umm...7? seriously? come on... this is awesome

Heck yes
1. battle against a true hero
2. FINALE
3. death by glamour
4. SAVE the world
5. either megalovania or ghost fight

I really love this theme. It's my favorite. And I also love the meaning of the battle. Through out neutral route. We see her commenting on how much she hates humans. Yet now she is protecting them.

Such a sad and heroic song!

Feel kinda sad every time hearing it because SPOILER ALERT! you have to kill undyne to win

My top 10 is:

It's catchy and it's in 2nd place in my top 10.

It is so fun to listen!

It's really catchy!

Just the right balance of awesomeness and hard-coreness

IT'S SO GOOOD

The only logical answer. - Brobusky

Haha really funny

Underrated, you can hear all of the themes of Asriel/flowey in this, and its amazing.

While this isn't for the best ending of the game, it's definitely a great final battle song.

Probably the most underrated theme. It’s fairly simple, yet powerful

I <3 love love GOAT MOM!

TORIEL IS THE BEST

YEAH GO GOAT MOM! WE <3 YOU!

The best in my opinion and a more epic version of hopes and dreams

Amazing yet another reason why I love it

Just amazing

This is just as good as death by glamour
So why is it 15

I want this at my funeral.

I wish this was higher - Maya159610

None of the people voting on this list have actually heard this theme, have they? - xandermartin98

I really like it because its just so edicting and it much better than dummy!

Just so addictive!

I think this should be in the actual game. This is magnificence.

DO YOU WANNA HAVE BAD TOM - Yendks

Kinder Sans:DO U WANT 2 HAAAVE A BAD TOM! Kinder Frisk:no

It's A MEME BY SR. PELO

Amazing inktale megolovania. *claps*. Wut a masterpiece yuuush! *Humming tokyovania intenseifies*

Is this Endogeny's theme? Because it sound like dogs getting abused.

Sans is probably one of my favorites. You could hum this all day!

Surprised nobody mentioned it, I adore how this one gives kind of mid-20 century futuristic vibes

Somebody Included Alphys takes action, so I added the best remix of megalovania and backbone I have ever heard by far.

I added this because I like Toriel and classical music

I LOVE THIS SONG!

In my opinion the worst boss theme. It's just too repetitive.
