1) Heaven (DJ Sammy and Yanou)
2) Sweet Dreams (You'd better know the artist)
3) Butterfly: Upswing Mix
4) Candy: Heart
5) Volume 4: Raver's Mix
6) Dam Dariram
7) Beethoven Virus (Pump it Up)
8) Candy: Star
9) Wonderland: UKS Mix
10) Csikos Post (Pump it Up)
11) Dr. Mario's Theme (Smash Brothers Melee)
12) Going to Suzuka: Shoemaker Mix (S&K)
13) Heaven is Place on Earth: Speedo Mix (Wildside)
14) Ika Uka: E=MC2 Mix (Jenny Rom)
15) Bitches (Mindless Self Indulgence) <---hard as hell, Heavy only and if you've never heard the song the nearly random pauses will kill you.
16) 2002 (Tiger Yamato)
17) History of DDR (DJ Slash & the DDR All Stars)
18) Megaman X Theme (Ummm...duh?)
