of course i would like to DDR to some "Roman my dear boy" at the arcades as well... somehow stepmania at home doesn't cut it.
Find somewhere with an ITG cab that runs a hacked version and get them to add it in ^^
Anyway, my generic "favorite music game song?" reply:
DDR: most songs by Orange Lounge - Mobo☆Mago, Love is Orange, Mondo Street. Enjoy BeForU - Break Down! a lot. Also absolutely love yu_tokiwa.djw - Murmur Twins. If you go back to old arcade mixes then Lee Jung Hyun - Ba Kkwo and Wa, Smile.DK - Petit Love, Sung Suk - Space A, Duke - Starian, and Bambee - Bumble Bee.
PIU: Drunken Tiger - Emergency, Lexy - Greenhorn, Banya - Canon-D, Duke - Starian, Cachy Huang - UpUp, and Tashannie - Don't Bother Me.
ITG: Takoyaki - Go 60 Go and Nini - Little Kitty Mine.
