Red Velvet's Pose has multiple, extended rap sections where music just stays in F for 8-9 bars. Which is fine with the vocals and all other instruments, but just with piano, it's boring to play and even more boring to listen to. And my brain was not prepared to come up with new melody for almost 1/3 of the song.

So I decided to replace these sections with bits and pieces from Mozart's Symphony No.5 K.22 Allegro movement.

Enjoy :D
