I've never really understood the propensity for the overly exaggerated accent especially in modern country bands. There's plenty of C&W without such put on accents, Marty Robbins, Alan Jackson (there's a twang but it doesn't sound ridiculous), even some of Hank Williams stuff doesn't have that thick of an accent. A lot of the modern stuff sounds like they're singing a pastiche bordering on parody of the "country accent". About the only accent I can put up with currently for much time is Sturgill Simpson. As far as country rock, I'd far prefer without the accent more like Commander Cody or Doug Sahm.
