What are some good country music songs/artists for a rock fan?

I've been branching out a bit lately. I've really been just a rock fan my whole life- everything from The Beatles to Led Zeppelin to Bon Jovi to Social Distortion to Nirvana to Linkin Park to Incubus ...you get the point. I'm just trying to dip into some country music and I'm looking for suggestions. 10 points up for grabs, thanks in advance.
