RBN songs are still very new. It's not surprising some features simply don't support these songs. This may change for RB3, but even if it doesn't, I'm pretty happy just to have these songs in general. HMX can only release so many songs a week, so there was no guarantee we'd even get these. And if we did, we probably would've had to wait a while. Honestly, I bet that's why some bigger names, such as Third Eye Blind, decided to go with RBN. This way they get their songs out there sooner.
