FYI, with Orb (
MyCast your digital media with Orb 2.0 remote pc access software) and Windows Media Player or (better yet) TCPMP you can access a bunch of internet radio stations. (I think there are 303 by default in Orb and you can add more if you can get a URL. I added one I found on Shoutcast.com.)
And it can do a lot more then that. The downside is that you'd have to run Orb on a PC and have that PC running. But you can access audio/video files on the PC, audio/video on the internet, and a lot more.
