Velvet Revolver, Foo Fighters Guitar Hero III track packs hit Xbox Live

We think the signs are pretty clear now that Activision isn't taking the threat from Rock Band lying down. Just a bit more than a week after Guitar Hero III was released, we already have two meaty song packs to download through Xbox Live and enjoy.

For 500 points ($6.25) you can get either a Foo Fighters pack that includes "The Pretender" from the new album "Echoes Silence Patience & Grace", "All My Life" and "This Is A Call" or the Velvet Revolver pack, with "She Builds Quick Machines","Slither" and "Messages". Each of the packs are by the original artists. With a nice boost like this to the track listing before the old songs have even gone stale, it's clear Red Octane is playing for keeps. ... You may not want to count Guitar Hero out just yet.

Update: Activision has also announced that boss battle anthems and "The Devil Went Down to Georgia" will be downloadable (for free!) later this month for play outside the game's Career mode.
