New to the online marketplace this week are a demo of EA Tiburon's NFL Tour '09 (PS3, X360) and the several $1.99 to $2.49 keys that immediately unlock several otherwise attainable vehicles in EA Black Box's Need for Speed: ProStreet.

Today's update also includes the downloadable tracks for both Harmonix's Rock Band (PS2, PS3, X360) and Neversoft's Guitar Hero III: Legend of Rock (PC, PS2, PS3, X360, Wii) that appeared on Xbox Live late last year.

Rock Band musicians net eight new tunes from Lynyrd Skynyrd, Rush, Black Crowes, All-American Rejects, and others. Prices for the tracks range from $0.99 to $1.99.

Guitar Hero III rockers, meanwhile, gain six new tracks, including songs from The Used, Linkin Park, and Extremoduro. The three individual songs sell for $2.49 a pop, while the other three are bundled together for $6.25.
