Don't know if this has been listed. It's called the DJ Player. It plays continuous music and you can select the category. I'm listening to folk right now: Nanci Griffith singing Richard Thompson's "Wall of Death." They also have a Delta Blues category. Audio quality is just barely acceptable, and the audio stream is broken frequently if you are using the net for anything else at the same time. It is free and it is promotional of course.

Next in line tonight is John Prine singing "Space Monkey", perhaps in honor of John Glenn.
