That's what this New York Times story about Nashville (Tennessee) as "Nowville" (per GQ Magazine) asserts. Journalist Kim Severson suggests that country music has become a "national darling," and she does so amidst laudatory comments regarding Nashville's many amenities. Severson associates the phenomenon with the past few decades.
Certainly I am aware that country music is not treated with quite the obloquy it was--especially on the coasts--several decades ago, but a "national darling"? I'm not so sure.
