I rented this, was looking forward to downloading the tracks to my Rockband 2 library, but you need a download code to do this. So basically it was useless for me. Why rent this out at all...I don't get it. You can only acquire the code from retail packaging. Weak
With the ability of being able to download songs on xbox live this disc becomes obsolete. The only reason anyone would need this is if they couldn't get enough of Rock Band and were played out on the songs that came with the game, but did not have access to xbox live.
Buying an entire disc of 20 songs, only a few being worth playing, becomes less appealing when you can pick and choose only songs you would like and purchase them through xbox live.
