PASS. Horrible DLC again. Where is TOOL?

Cool. Pantera is bound to be some good finger exercise. More metal.

I bought Mouth for War just to have some 90's metal in my library. I can confirm that as you'd expect from a Pantera song, it's super repetitive and chordy, but also really fun :D

I wish they would put out more songs from Foo Fighter's new album. I want more than just Rope and Walk.

Totally picked up that Frampton track, wayyy better than the studio version. 13 epic minutes.

@Vigorousjammer: Dude, heck yeah, the live version is classic and a total blast to play. I don't like Frampton, but I bought that track the second it came out. Keys are especially fun.
