[quote name='hotwls13']What do you mean about the Export?? Is that something to do with Live?? I'm new to Live and I bought a Rockband 2 Set for my son for Christmas.
I also heard something about paying $5 for the Rockband 1 content, but I'm not sure how all that works?????[/QUOTE]
For $5/400 MSP, you can copy the majority of the Rock Band 1 content to your hard drive (all but three songs: Enter Sandman, the Paranoid cover, and the Run to the Hills cover). You could rent or borrow a copy of Rock Band to take advantage of this option.
Lego Rock Band is slightly different: It also has an export option - which, to the best of my knowledge, includes all songs - but the cost is $10/800 MSP, and you'd be best off using a copy of your own, since you need "a unique code included on a paper insert included in the game case" (precise wording borrowed from Wikipedia).
And yes, if it wasn't clear already, you need to be connected to Live to do this
But it doesn't require you to have XBL Gold, if that's any consolation.
