I always like to hear what the local stations are playing. There aren't as many local stations as there used to be, but Nashville must still have a few. And public radio and community radio can be lifesavers. I highly recommend going to NFCB to find the community stations in your flight path. For driving, I like perky stuff with entertaining playing and lyrics (e.g. Aretha, Elvin Bishop, Ry Cooder, Dead, Dire Straits, B.B. King, Kinks, Etta James, Sam and Dave, Stones, Richard Thompson). I've had a Crusaders tape going in the car lately, but in general, I don't like jazz while driving. It's too much like multi-tasking!
