How do I unlock more songs?
I have two unlocked already. Do Dark Notes help? I've played some songs in the Chaos Shrine that aren't in my Challenge Mode. Can they be unlocked in Challenge Mode? I'd rather not risk pulling a hand muscle in the Chaos Shrine every time I want to play them. Le_Chevalier - 8 years ago
You unlock songs by amassing Rhythmia - you CANNOT get them by playing Dark Notes (well, you can, but only because you gain Rhythmia when you play them). Check out the "Cheats" section of the game here. It tells you exactly how much Rhythmia you need to unlock each song in challenge mode. iambasho - 8 years ago
Basically from what I've seen so far, you can unlock songs by A) gaining rythmia or B) playing them in Chaos, though I'm not sure if playing songs in Chaos will unlock them in challenge mode or not gman78676 - 8 years ago
