Microsoft has just announced that they will be adding a special area on the Xbox Live Music section on the Dashboard for Rock Band , Guitar Hero, and LIPS, allowing people to browse songs without having to load up each game's individual in-game stores.
As with the in-game stores, you can search and sort though track, as well as listen to previews of the songs before you buy them. The games benefiting from this update are Guitar Hero 5, Guitar Hero World Tour, Band Hero, Lips, Lips: Number One Hits, Lego Rock Band , The Beatles: Rock Band , and the regular version of Rock Band .
According to Microsoft, Xbox 360 owners should see the section pop up in their dashboard later today.
