WTB: Account with any Rock Band Legacy DLC

I simply want to buy an Xbox Live account that has any of the exported Legacy DLC on it from Rock Band on Xbox 360. I preferably would love to get RB2 the most, but I will gladly take Lego, or Green Day. I've already got the RB1 and RB3 exports, so I have little use for those without any other exported tracks from other games on the account.

Got an account with any of these Rock Band treasures you're looking to part with? I'll buy'em.

We will negotiate the terms of the transaction after I have spoken with any potential sellers.
