I don't know many. I used to play officials on keyboard ages and ages ago, but I've long since forgotten most of them, plus, i transitioned frm the easy heavies to the hard ones pretty quickly, and have never been a fan of playing easier stuff than I'm capable of. I tend to do poorly when I play DDR on my home pad simply because I never play a warmup (doesn't help that supernova's unlock style pisses me the fuck off, because I simply cannot play songs at 1x speed now.)
