When I was a young warthog and reading the Bleach manga, every few chapters or maybe once per volume there would be a character bio page for a different prominent character of the story, like a little character sheet. Their height and weight, their favorite food, names of family members, their theme song. And that last one got weird, because while the central characters were living in 2000s Tokyo, a lot of characters lived in perpetually feudal-Japan spirit world, only briefly visiting 2000s Tokyo while working. The page of one such character, Byakuya Kuchiki, had his theme song listed iirc as something by Radiohead, which instantly bothered me. Why does this stoic feudal Japanese samurai/shogun have a theme song from probably 1990s England? Not that Jpop would be any better, but it seems anachronistic and misplaced. Anyway, my question for my fellow character-makers is this: how do you decide your characters' theme songs? Do you try to choose what they would like in their own setting, or what they would like if they lived here today, or something you like that you think fits their personality regardless of their own taste? Do the words matter or not? Do you just look for a punny name (like how HeroofFire101 sort-of suggested mine to be this, instead of this), or are these just murky waters that you vehemently choose not to wade into?
