OK, I'll start it up.
The ClubIt feels like Project Gotham with guns...I'm not kidding. It's fun, worth the $11 I paid for it, just not as good as the demo made it seem. Still the best part was talking Gamestop down from $40 to $11 for a used game

PURE demoGot it for preordering, best extreme sports game I've played since SSX 3.
21st Century Drum & Bass (Mixed by Decoder)Decent old school techstep mix circa 2000 by Decoder, can't really complain considering it's a 3CD mix of classic tracks and I got it in good condition for $1.50. Was worth the effort.
Calyx & Teebee - Anatomy Best Drum & Bass I've heard in nearly a decade. Very dancefloor oriented but works really well in Geometry Wars 2, and the PURE demo.
