Rock Band Unplugged will feature over 40 master-recordings including nine exclusive new songs that will debut on the PSP system before being offered as downloadable content for console versions of Rock Band. Plus, Rock Band Unplugged will include the first fully-featured in-game store for downloadable content on the PSP system in the North American and European markets, leveraging the PSP system’s wireless capabilities. The in-game store will be powered by PlayStation Network, and players will be able to use their existing PlayStation Network account to purchase tracks, similar to the Rock Band console experience. PSP system owners will also have the option of purchasing tracks via PlayStation Store on the PC.
