The music store allows for purchase of a number of new tracks from the Playstation Store on the PSP. The amount of songs available is meagre but it is available when more is added. The 41 songs on the UMD is enough to keep an interest in the game, despite a little repetition in tour mode. The mixture of different styles of tracks also adds to the approachability, with a mix of soft and heavy music. Rock Band: Unplugged excellently combines a music rhythm game with in a portable device and should entertain fans of the console version and commuters looking for an engaging game.
