Honestly anything originally released prior to the explosion of Rock and Roll is true Country music. Anything after is Country Pop or Pop influenced to a degree. Most country music fans have their core sound that they enjoy which they consider true Country Music and anything outside of that (barring a legendary artist or two) is Country Pop and shouldn't be listened to at all.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
