I'm wondering if maybe it was a mistake to have separate RBN and regular Music Stores. I personally don't mind. But for the average Joe, combining the stores would make it easier to find that Artist that you want. Say you want to find The Shins: you have to check both stores to get the 3 songs of theirs. Kind of a hassle, and I wouldn't be surprised if they just saw the 1 regular Shins DLC in the regular Store and left it at that, without even checking the RBN store.
