I just need a few DDR songs that weren't on the site...these are all from Dance Dance Revolution Extreme 2 but I've also listed what albums they originally came from. I'm kind of of a DDR song n00b, so let me know if these are unavailable or something like that, thanks a bunch....

sync (EXTREME version) - Outphase [GAME D.D.R.: Dance Dance Revolution EXTREME]

Butterfly (Upswing Mix) - smile.dk [Dance Dance Revolution 3rd Mix]

Polovtsian Dances and Chorus - Naoto Suzuki feat. Martha - [Dance Dance Revolution Extreme 2 US]
