is there any particular reason this has happened to me 3 times each time i play the game? i haven't downloaded any new dlc! it takes so long, even when i first played Rock Band 2 after ripping Rock Band 1, it didn't take this long, and only needed to do it once... is anyone else having this issue multiple times? kinda makes me want to use the Lego Rock Band disc as little as possible due to all the loading. I'm using the XBOX 360 version btw.
