There are a lot of types of country and a lot of different singers. Radio USA certainly doesn’t represent all of it.
It’s like saying you have to be a punk or a lower-class African American to enjoy rap. Rap is surprisingly varied, done by basically all nations and ethnicities, and more-often-than-you’d-think political or otherwise intelligent. Linkin Park (and the spin-off project Fort Minor) is my favorite band, for example; and most of their rap is about politics, introspection, dealing with mental illness, or putting down bad relationships— and the latter can be angry, melancholy, resolved-and-hopeful, forgiving, and anything in between. But I digress.
A genre is just a genre, and any genre can be smart, skillful, and all-around good.
