That's an interesting question to be honest. Though I do would say my OC's have different tastes in music.
Seraphina: Musicals, upbeat pop songs, inspiring emotional pop and rock music
Hyoko: Punk and lots of rock n'roll. Sometimes metal (because he is edgy)
Chiaki: Instrumental Japanese music and J-Pop
Siara: Classical music with a sprinkle of oldschool swing music
Arthur: His taste in music is hard to figure out since he is mostly in nature. Does bird's songs count? sometimes he might listen to some pop music that is popular at the moment but very much prefers pop songs from the 2000
Vesper: Old sailor songs, musicals, 70's & 80's music
Celeste: K-Pop, Metal and alternative rock
Michael Rock and Metal (surprisingly)
Gabriel Popular Pop Music with a twinkle of rap from time to time
Uriel Classical music & instrumental. Play metal or rock and he will smash your radio/phone
Raphael Traditional irish folk songs, happy pop-songs
Azrael Hardcore metal and the occasional classical music
I do think most of this fits them very well. Either way it was very interesting to think about this!
