rdio Offline Desktop Sync

Probably should've been working on some other projects but my internet went down for a bit and realized that rdio doesn't have an "offline" sync to desktop. I upgraded to premium back in July (extremely pleased with the service) but my phone is running out of space as I have nearly 15 playlists synced. Threw this together pretty quickly

Tried staying consistent to their current style as I'm a huge fan of their mobile app. Would love to see this feature sometime in the future
