This is a little gem here. It has 11 songs from the game, well...Guitar Hero 3. It's mainly just a compilation of existing songs, which were used in the game, but there's some rarer stuff like Steve Ouimette's excellent reworking of "The Devil Went Down To Georgia." Here's the track list:

3. 3's And 7's by Queens Of The Stone Age
