There are roughly 30 background tracks in the game used for cutscenes and to set the mood when two characters interact. All of the music was taken from girls-go games or games with an anime aesthetic, if you can create tracks that fit the feel of a typical "girls-go game" or "gooner-bait anime game" that would be cool
