Mikan can access a list of soundtracks by interacting with a book on the table in her bedroom. By selecting the Music tab, the player can view soundtracks they have unlocked through exploration, as well as a few tracks that are available by default. Soundtracks are sorted by CD colors that indicate which artists composed them.
Do keep in mind that Braingirl is a work in progress; as such, this page is subject to further changes across future versions.
