Strrreaming Radio

I keep getting sick of my own music and wanting to hear something that might not necessarily come up on Pandora or Last.fm, but have only found a few good ones out there. SomaFM is an interesting one with ambient music that might be good for the background. WOBC will always have a special place in my heart and be my go-to when Car Talk comes on NPR, but when the folk shows come on, I can't really take it. Casbah Radio and Oh-la-la were recommended to me by a coworker, and are pretty great but I want more! Send me your tips, please.
