I've recently found out about radio paradise which I'm listening to via my apple itunes software. It can be found at radioparadise.com. It's playlist is quite varied but I've been finding I like most of the stuff they play. There's a whole bunch of tracks that I'm going to hunt down after listening. I really liked Bela Fleck's track "gravity wheel". I've also got into listening to Vida Blue who are a spin off from Phish. Really nice phreaky jazz sounds with a solid funk groove - highly recommended.
