I can understand the AC/DC and Track Pack ones...you buy the game, enter the one time code, that makes sense to me. The original Rock Band export was awesome, pay $5 export the disc. But Lego is the most ridiculous one. You're paying $50 for the game, and another $10 for a one time only export...what the hell were they thinking!? Instead of getting $10 from me, they're not going to get anything.
I hope they release those songs individually, because I'm not paying $60 for 7 or 8 songs I want.
