I recently bought an XBox 360 along with Rock Band 1 & 2. So far I love it! My husband purchased a DLC song but can't find it listed in either Rock Band. I have searched and Google'd high and low to see what we're missing. Do we need to install it somehow? If so, how? I apologize if there is a post about this somewhere but I can't seem to find it. I feel like a great big idiot right now because I'm sure it's something simple. Any help is greatly appreciated!
