Any ideas for songs I could play on the radio?

Doing this 2-hour radio show every Saturday and Sunday afternoon. The station generally plays hits, and goes for this hip, trendy sort of image.

I generally listen to old rock classics, which is also what I play on the show. But last time I went a bit too far and played Jazz (as in a bunch of people in suits blowing trumpets in the 30s). Some of it was too slow.

This week I’m thinking of playing some country and some southern rock. Does anyone have suggestions? I’m looking for specific songs that are well-known (a couple of unknown gems are fine, but they generally have to be international hits). Preferably newer stuff, definitely clean recordings (Allman Brothers Live is out of the questions). Maybe some country-rock tunes everybody knows but I’ve somehow missed?
