PLAYSTATION® ONLY: Can I play Rock Band downloadable content from one region on a copy of the game from another region?

PlayStation®4 is a region-based console, 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, say, the European Rock Band Music Store on a U.S. console and game, or vice versa, the download will not begin and will be inaccessible. In the event that you have purchased DLC for a region that does not match your game, please contact PlayStation Support.
