I'm not really a "country guy" but I really appreciate honest country and also honest western music. Most music is honest unless it is driven by the kingmakers, then it is usually a version of a formula likely to produce a profit...plain and simple.
I'm no professor, but my theory is that after the hay day of rock, styles like grunge and alternative rock just didn't step up to the plate. That, combined with the wholesale bullying of the entire american culture by the hip hop/rap, MTV machine left a really big void in popular music. Modern country, as fake as it is, filled that gap and it's basically the new "rock" music. Non-country types can tolerate it because it rocks, country folk tolerate it because it's better than nothing, and it ain't rap.
The fact is, these big country stars have talent, but Tim Mcgraw, Toby Keith, those type of mega stars are a commodity, like any other commodity. God bless them, they've gotten rich on what they're doing, but, to quote Walt Welch (a life long, not famous, not rich, country bar guitar player) "It ain't country".
I don't have a country voice, but I've been working on it in my single acoustic act. I've always done a wide variety of music so I so some country and folk. "You are my sunshine" is actually a sad, beautiful song. I've got a couple of Bob Wills songs, Merle, Johnny Cash, but my audience is not country so I can't overdo it. The thing is, that music is honest and clean and it was meant to express a thought or an emotion, not to make a million dollars. I guess that's the difference.
I think you'll have a hard time finding real country in arenas. You're going to have to ask around and find out if anyone knows of any good local country musicians, then go patronize the roadhouses, restaurants, and dives that pay them lousy money to bare their souls night after night. That's where the real music went.
