I find it interesting that, in this case, de-regulation is being blamed for the lack of diversity. According to most of the de-regulation arguments, "open markets" foster competition which brings us lucky consumers more choices. How will the de-regulators (most often from the Republican camp) spin such obvious empirical evidence refuting one of their primary arguments?

By the way - Nashville has always tried to exclude what they couldn't control. That's why you rarely here Waylon or Willie on the radio, and why the best country music comes from Austin, Texas and has for a very long time.
