I have three Rock Band track packs for the 360 that I don't need anymore. The codes have been used so the songs can't be imported to RB1/2, but each pack is fully compatible with all RB and GH instruments, and has a full 1000 gamerscore.
Track Pack Vol. 2
AC/DC
Classic Rock
Located in Calgary, and accepting pretty much any offer on these.
