Yeah, I spent my teen years in West Virginia, and when I was a kid, in Louisiana. I definitely have that exposure to two different sorts of rural: the South and Appalachia.
I listen to KCRW in the car and Pandora radio, which I stream through the stereo from my iPhone. I've been listening to everything from Caribou to Conway Twitty. If I'm going on a longer car ride, I'll download some podcasts.
