I'm not sure if LSMJ is correct in the composition credits for tracks 2 & 3, because those artists didn't actually compose any BGM for the game? None of the song titles actually match any BGM tracks either (although maybe they're just new names).
Not sure about the romanization of エディア in the title, apparently the game takes place at エディア・ローファ樹理学園 or something
