Want a chance to get Free Rock Band songs? Pepsi is currently running a promo in conjunction with the upcoming release of The Beatles Rock Band. On Pepsi bottles and 2 Liters, look for the yellow caps with the different RB logos for codes to enter on the site Here. Keep in mind that each code is a chance to win free DLC but the odds are good. I entered 11 codes in earlier today and won 6 songs. Codes are good toward 360, PS3, and Wii (less choices) versions. The Drink Up Rock Out promotion ends on Sept 13th. So give the site a look and see what other prizes you could try to get. Good Hunting.
