So IIRC Kubo picked out theme songs for a bunch of characters, though the only ones I remember are "News from the Front" by Bad Religion for Ichigo, "Superpredators" by Massive Attack for Kenpachi, and "Mars, Bringer of War" by Gustav Holst for Yamamoto. Do you have any music that you associate with your versions of the characters?
Hmmm... Granted, my audio processing issues mean I have genuinely weird taste in music and even weirder musical associations but sure, why not:
Ichigo: Tokyo by The Wombats
Orihime: Madamoiselle Juliette by Alizee
Chad: Light it Up (remix) by Major Lazer
Tatsuki: Karateka Teusday by Robbydude
Mizurio: Putty Boy Strut by Flying Lotus
Keigo: DOTA by Basshunter
Kon: Jazz Arrangement of "In The Hall Of The Mountain King" by Samuel Evans
Kenpachi: March of Cambreadth by Alexander James Adams
