Harmonix CEO Alex Rigopulos announced that Rock Band has some serious plans for delivering content to players. First off, Harmonix plans to release new music tracks every week. They can be released in singles, multi track bundles, or more deliciously, full albums. As an example Alex announced that The Who's Who's Next would be available for download following the game's release.

As icing on the proverbial cake, selections spanning Metallica's musical career will be made available, with "Enter Sandman" playable on the retail disc. All in all, Harmonix is pushing Rock Band more as a platform than just a game, and we couldn't agree with the prospect more. We'll be back with hands on impressions and a proper tribute to Weezer as soon as we can.
