Xbox Live Marketplace entries for music game DLC, but now each game will be receiving its own themed store. So, if you want to pick up Rock Band or Guitar Hero tracks, you can open up the corresponding store and start browsing. Each store will also allow users to preview songs, so there's no need to fire up each game to see if you like a particular track.
The stores should be going live sometime today, so keep an eye on the Music Marketplace section of the Xbox 360 dashboard. The games that will feature their own stores include Rock Band, Rock Band 2, The Beatles: Rock Band, LEGO Rock Band, Guitar Hero 5, Guitar Hero: World Tour, Band Hero, Lips and Lips: Number One Hits. Check out images of the new storefronts in the gallery below.
