Can I play European downloadable content on a U.S. console and game?
Rock Band games are regional, so you will need to make sure that the game, console and DLC you are attempting to use are all the same region. If you attempt to download songs from the European Music Store onto a U.S. console and game, or vice versa, the download will likely be unplayable. This also applies to Asia and Australia regions. In the event that you have purchased DLC for the wrong region, please contact your console's customer support (Microsoft or Sony) to look into an account adjustment.
