I'm with Paulie on the newer country. Too much pop. That's why I tend to go out of the mainstream for my country music. Bands from the Texas/Oklahoma area: Cross Canadian Ragweed, Jason Boland and The Stragglers, Reckless Kelly, Micky and The Motorcars, Cooder Graw (they just broke up), Eli Young Band, The Kene Terry Band (from right here in Nuevo Mexico), Shooter Jennings (Waylon's son), Honeybrowne and the list goes on and on.
I also agree with Tyler on the Outlaw Country. Especially the older stuff, Waylon, Willie, Merle, Johnny Cash, Kris Kristofferson you get the gist I'm sure.
