There's also the Pagan Radio Network, which features live streaming music from a variety of Pagan artists -- folks like Emerald Rose, Daughters of Gaia, and more. PaganWorldRadio is also available online.
Finally, even Youtube can be a good source for discovering new Pagan artists. Go to Youtube's home page, and type in "Pagan music" in the Search bar -- you'll be amazed at the vast selection of stuff that comes up!
