Say, on the PRO side, I've not seen anyone mention everyone's favorite long-haired country boy...Charlie Daniels. I'd buy his stuff anyday.
Gonna try to find his book ("It's Not A Rag...") for Christmas...gift to myself!
There's also Sara Evans, Martina McBride, Toby Keith, Daryl Worley, Alan Jackson, 3 Doors Down, AAron Tippen, Faith Hill, Kid Rock, Meat Loaf, etc...
