@tyray I live in the Charlotte, NC radio market. And much like Charlotte itself, the radio offerings are pretty cookie cutter. In fact, its a wasteland. At least in terms of rock/indie etc. I don't know about jazz. I still scan the channels in the car but you are not going to hear anything new or interesting on Charlotte radio stations unless I'm missing something after being in the area for 25 years.
One exception is WDAV out of Davidson College. It is a fantastic classical music station. I'm only marginally into classical though.
There is an oldies station south of here that is pretty good. They occasionally play stuff I've never heard from the 60s and 70s..........but there is a catch.......the reason I haven't heard most of those is because they are AWFUL. ;-)
