All of the music is like that.
Especially the human bosses, with the song that randomly has the singers singing what sounds like "Sophia!"
The music is so, so good.
Yeah the music is so good that I had to find a way to rip it from the game to listen to it at work or just doing stuff, I love games OST in general and this one is really great.
Each battle music has 8 variants:
- the default one with voices
- a voiceless one
- a "muted" one (when calibrating your position)
- one that plays when ab-guarding I think
- two catchy ones with different clap rhythms (used for rhythmic moves)
- one soothing version for yoga moves
- one like the default one but with more instruments, a bit catchier (harder moves ?)
It's great how the game switch to each variants seamlessly.
I love the Boss one against Drago.
