Here in Southern Indiana/Louisville, for a while we had the endangered species that is a non-sellout Commercial Radio station, LRS 102 The Walrus. While they played commercials, they were locally owned/ran, played a great and diverse playlist of modern rock, not just stuff "programmed" to generate the maximum number of 18-49 male listeners for ad revenue. They played local bands, sponsored local shows. But then they did sell out to Clear Channel... they're still around, but it's the familiar "same 50 songs over and over" playlist, nothing terribly unique to it.
I guess the only decent station left is <a href="http://www.wfpk.org/">91.9 FM</a> Jazz and adult alternative. Lots of good stuff... no commercials, plus they air "Le Show" with Harry Shearer.
