I'd recommend streaming 89.3 The Current from Minnesota Public Radio.

http://minnesota.publicradio.org/radio/services/the_current/

It's fully independent music radio station that's publicly funded. They don't play commercials, and they play a wide variety of known and unknown music. I first discovered it when I moved up here (the Twin Cities) away from the Clear Channel dominated airwaves and I haven't turned back since.

Couldn't agree more. I discovered 89.3 when going to school in the cities. Now, even though I no longer live in the area, I stream them online almost every day.

Milwaukee's got what sounds like a similar station: http://radiomilwaukee.org

Broadcasts at 88.9 FM in the city and streaming at the site.
