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.
