Rock Band Blitz hosting tournaments

Prove you're the best at manipulating Rock Band Blitz's power-up combinations, by competing in a new series of weekly tournaments. Harmonix has added the option to enable tournaments on the Rock Band World Facebook page, after which you'll be able to play the three tournaments hosted every week.

Each tournament focuses on a single song, and allows you to replay the song as often as you want within that week to get a high score. If you have the highest score or the second-highest, or you're one of three random winners selected for each song, you get "free DLC and other great prizes!"

The tournaments continue through March 13. This week's eclectic challenges: "Don't Let the Sun Go Down On Me," "Charlene (I'm Right Behind You)" and "Shout."
