I can't seem to find an answer to this anywhere

So, does anyone know if I can download subscription tracks from Rhapsody and play them on the J3, or is it strictly non-DRM tracks period?
I've used Rhapsody to listen to a variety of music, especially for researching new bands, etc. for years now, and it works perfectly with my Sansa Clip and Fuze as well as my Walkman 545.
While I adore the players mentioned above, I do feel like I want to take the next step up and pick up a Cowon J3. I already have a lot of music I've ripped from my CD collection and have purchased online, but it is still nice to be able to download subscription tracks from time-to-time.
Thanks in advance for any help!
