Retailer GameStop recently updated their listing for Rock Band Unplugged with box art. Good for them! Even better, they're all like "view back of the box," which reveals all kinds of juicy information on the PlayStation Portable title -- stuff Harmonix and MTV Games haven't talked about yet.

For one, it looks like there will be a single-player World Tour mode that will include 24 cities; based on the picture, it has a similar aesthetic and set-up to the one found in Rock Band 2. The game will also support downloadable content along with an in-game Rock Band Music Store. However, it appears there will be no online or multiplayer support.

Additionally, the art claims the game will have over 40 tracks, all masters. 15 songs are listed, many already playable in the console versions of Rock Band. Which ones are new? 3 Doors Down's "Kryptonite," AFI's "Miss Murder," Alice in Chains' "Would" and... The Jackson 5's "ABC."

All 15 revealed tracks can be found after the jump.
