There's a reason country bands who wanted to produce their own sound and play their own kind of music have started their own labels, or gone to small, indie labels.
What we called "country" when I was young is now "Americana" or "roots music." Consequently, it has no place in the mega publishing houses. I was shocked beyond belief when the Alabama Shakes did so well. They're innovative and don't sound like anything else on the market. How in the world did they manage to get a contract and any kind of promotion? They're home folks, so I'm thrilled. But it's still amazing that it happened.
