Rock Band Unplugged features over 40 master-recordings that include nine exclusive songs for the PSP system (this is only for a limited time…) Rock Band Unplugged will also 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 is powered by PlayStation®Network, and players can 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.

The following tracks will launch exclusively through Rock Band Unplugged on the PSP system for a limited time before becoming downloadable content for the other platforms:

• 3 Doors Down – “Kryptonite”
• AFI – “Miss Murder”
• Alice in Chains – “Would?”
• Audioslave – “Gasoline”
• Black Tide – “Show Me the Way”
• Blink 182 – “What’s My Age Again”
• Freezepop – “Less Talk More Rokk”
• Jackson 5 – “ABC”
• Tenacious D – “Rock Your Socks”

You’re not going to need a PSP to get songs for Rock Band on the Playstation, but it’s going to make it easy and simple, and that’s a good thing any way you look at it.

With all of this, the one thing you’d expect to see (but DON’T) is multi-player capabilities. There’s enough to make this title worth it if you have a PSP, but if it added mult-player, it might have people buying PSP units just for this game.
