No. You need the RB1 game disc. Make a friend/rent/buy. Then launch RB1. under options, there will be an export function. It'll cost you 400 MS points which is $5 I believe. The entire RB1 collection, excluding Paranoid (black sabbath)/Run to the hills/Enter Sandman, will be moved to your hard drive. Then you can go back to Rock Band 2 and see all the RB1 songs there.
