It's hard to blanket the new age of country stars, since few of them write their own songs, so you cant put anyone into a certain 'group', as what they sing doesnt equal what they feel/think.
I actually like Big & Rich, although they are a far cry from the traditional country music i prefer/generally listen to.
At least they have their names on the songwriter line of the album. Same as i like Alan. Toby is a semi-songwriter, but he presents it well, and i like his style. George is great, he's a singer, not a songwriter, but he sings Chris Ledoux songs like they are his own, he's the only country singer on the main stage who can handle a cow horse, a Classic rope, and a jumping steer.
The Tim/Faith/Kenny country is just pre-formed hit garbage, i can't stand to listen to it. Kenny is better that the others, but his songs often turn me off after 2-3 listenings. If i want to listen to Jimmy Buffett, I'll listen to Jimmy Buffett.
Personally, i listen to alot of Texas singers, Cory Morrow, Pat Green, Dub Miller, Rodney Creager, et. al., as well as Shooter and Hank III,, thats more country than the Tim/Faith crap we're subjected to on the radio
