I much prefer Rdio
over Spotify. It's the same cost with a much better interface. For example, with Spotify you have to launch a program on your desktop to use it, whereas Rdio is all web based so you just open it in a browser, which is much more convenient IMO. On top of that, the app is way better. I have spent a lot of time on both services because my gf has Spotify, and Rdio is significantly better IMO.
***I was a rdio user long before this article came out
ETA2: the thing that sucks most about these services is that there is virtually no Beatles or Led Zeppelin on either one
