I believe there is a difference between generas of music being "dead" and genears of music not having mass popularity.
I play a lot of cafe jazz in the style Django and Grappelli- there is still stuff going on with it, but I could be convinced that it's not "alive and well" because there aren't a whole lot of new compoositions that get wide distribution.
And I really enjoy a lot of the hiphop, EDM, and other stuff I hear- I am not trying to make an argument that those aren't wildly more popular.
Given that there are new artists making a living creating new compositions playing coutnry, as well as large audiences paying money to listen and dance... it's hard to convince me the genera is "dead.
But keep in mind, that's not the argument I was making, that is an argument you're placing on top of what I was saying.
The claim I was responding to is "Country music was never good post the Johnny Cash era. "
I posted some musicians who I (and guessing by their ability to make a living playing new music, other people) believe stands as a counterpoint to that point.
So for all your concern about the legitimacy of my "argument", you're focusing on a claim I am not making- even if it were a "dead" genera, people are still making new music with enough support that they can make a living performing it.
