To start with, I preordered Rock Band 4 off of Amazon and received some dlc codes. I noticed a problem with it downloading the same few songs over and over no matter what I choose to download. I went through uninstalling the game and all it's dlc multiple times (weird thing is it'll only uninstall the songs it actually installed while the other ones I have to completely turn off the system and back on to uninstall). After reinstalling 2-3 more times I thought to try installing each song one by one, but ended up with the same result. This leads me to believe there's a problem with the dlc itself and I'm hoping to get that taken off my account so I can get a new code to redownload them with to hopefully work! This happened with two codes by the way.
