Everyone else seems to have listed the majority of people/bands I listen to
But you should also try Phil Vassar and Trisha Yearwood (Garth Brooks' wife).
Also, maybe shamefully, I quite like the album by Scotty McCreery (the most recent American Idol winnner, who has quite a good country voice, he could become the male Carrie when he matures a bit more as he's only about 18)
