I'm not super acquainted with the song list but I really like 8-EM (absolute favorite), Life, Climax, the yamaoka anime girl dubstep one... in recent updates I liked parvorbital, TECHNOPOLIS 2085 and Strange Love. there are other things I appreciate but haven't re-listened to all that much like the kikuo and owltree songs. it was cool in the recent songlist where they randomly hired hiroyuki oshima to do a fantasy anime BGM. most rhythm games would not do that
