Rock Band 2 but have found it difficult to follow the plot lines, we regret to inform you that you won't be able to simply download the songs you missed from Rock Band 1. Variety says the plan is to keep Rock Band on sale for the foreseeable future, so you'll have to buy the physical disc if you want to "Sabotage" "The Hand that Feeds" or "Learn to Fly" "Next to You."
Disappointed you can't just pay $5 to import the tunes like all your Rock Band 1 owning friends? We would kindly direct you to your local Blockbuster. Hint, hint.
