Top 10 Songs With the Most Unexpected Transitions

Transitions are used to create comical effects. It's a funny Jason Derulo cover where the singer (Anthony Vincent) changes the music style every 10 seconds (the reason he named the project Ten Second Songs). All transitions from one style to another are funny (20 styles altogether) but my fave transitions are between the styles of:
1. Aventura - Slayer - Bob Marley
2. Will Smith - Kataklysm - System Of A Down - Slick Rick (for me this is like the climax of the song)
3. Bee Gees - White Zombie - Hootie & the Blowfish (song sample features it)
4. Jason Derulo - ACDC - Ray Charles
5. Josh Groban - Muse

I didn't add this song but I realized it deserves to be on this list. Thanks to whoever added it.
The song structure is like a labyrinth in the wonderland - every part is different and transitions from one part to another are pretty unusual every time; there aren't verses in the strict sense and there's no chorus! So imagine the transitions.

It starts to sound like a completely different song!

Exactly! It's a multi-part song where every section is different and sections aren't repeated which might be one of the reasons some people can't understand and appreciate this song (music-wise).

The middle part of the song is just amazing.

It's great how it always changes genres

Heavy rock guitars followed by happy yodeling (play the sample). Rock fans don't expect to hear yodeling... That transition always puts a smile on my face.

False /fake ending in the first half of the song - much more is coming after the fake end!

Same deal as with November Rain, always gets me and I think it's a new song playing.

Amazing song

This one is pretty weird in terms of transitions, all sound funny to me

And that makes this song good in my opinion.

It's a hard rock song and the transition to the sax solo is unexpected because you expect a guitar solo. I love this song. And the sax in it.

A song with false /fake ending - when you think the song is finished, music suddenly comes back.

A power metal song where suddenly the singer starts singing jazz (singer is Tobias Sammet). But it doesn't sound bad to me. I love it. I was just O_O when I first heard that transition.

This song starts out hard with singing on the 1st half, then the other half is very pretty instrumental, like 2 songs in one.

After the false ending, music suddenly comes back.

A violin solo in an extreme metal song. Violins used in the arrangement aren't unknown in metal but a violin solo IS a pretty unexpected transition.

A long and soft piano intro followed by... brutal technical death metal. Most fans believe this is Cryptopsy's best song.

The transition to the "No one but me can save myself..." part specifically takes the song in a different direction.

When Dave Murray's solo starts (around 2'30), the rhythm becomes different compared to the beginning of the song.

This song is ten minutes long so there are many transitions. Especially around 4'00 with a quiet and peaceful midsection and from 8'05 till the end with a long singing section.

I mean the transition to the part where the lyrics are in a binary code - "01101000, 00010010, 11100010... " (and the singer sings "zero one one zero one,..."). It's a long section:
Zero (one) one (zero) one (zero) zero (zero)
zero (one) one (zero) zero (one) zero (one)
zero (one) one (zero) one (one) zero (zero)
zero (one) one (one) zero (zero) zero (zero)

Zero (one) one (zero) one (zero) zero (zero)
zero (one) one (zero) zero (one) zero (one)
zero (one) one (zero) one (one) zero (zero)
zero (one) one (one) zero (zero) zero (zero)

off (on) on (off) off (on) on (off)
off (on) on (off) on (on) on (on)
off (on) on (on) off (off) on (off)
off (on) on (off) off (on) off (on)
off (on) on (on) off (on) on (off)
off (on) on (off) off (on) off (on)
off (on) on (on) off (off) on (off)

no (yeah) yeah (yeah) no (no) yeah (yeah)
no (yeah) yeah (no) yeah (yeah) yeah (yeah)
no (yeah) yeah (yeah) no (no) yeah (yeah)

no (yeah) ...more

The first time you hear this, no way do you see the beat switch-up coming!

That part around 5'00 is quite surprising (and beautiful)

The part that precedes the solo

When the bass solo comes in...

One of my favorite moments in this song is namely the unexpected transition to that powerful scream, after 7 seconds of soft background music (around 2:00).
