I just ran across this thread.
My favorite station is KEXP in Seattle. Where the Music Matters. It is listener suported radio with basically no commercials and the best DJ's. John in the Morning M-F 6-10 and Sheryl Waters for The Midday Show M-F 10-2. They play all the best new and old independent music. I now stream online kexp.org, since I do not live there any more. They have hundreds of in studio live shows, free songs of the day, and other podcasts that you can download. Honestly, one of the best independent music resources out there. Better than KCRW. And, No, I do not work for them.
Usually, I lurk, but this I had to share.
