Seems like Store got updated today with the following (according to post on creators site, haven't verified it myself)
Song Title - Artist
I'm Made of Wax, Larry, What Are You Made Of? - A Day To Remember
50,000 Unstoppable Watts - Clutch
Business Time - Flight of the Conchords
Midnight Ride - Midnight Riders
Nothing There - Oliver Pride
Dirty King - The Cliks
Semi-Charmed Life '09 - Third Eye Blind
We Are Not Anonymous - Unearth
I'm up to 40 tracks to download!
Since nobody seems to have mentioned it, I believe "Collapsing" (Demon Hunter) passed peer review yesterday, so that should be coming in the next few days.
I was so expecting Business Time to be released on a Wednesday ;)
