All the labels people put on music stops it getting to new listeners.
Personally I can find something in all forms of music that I enjoy. My least favourites are rap or hip hop and modern jazz but I can find examples in even those genres that I can listen to.
Going back to folk music though - a lot of what Springsteen has done is "folky" even apart from the "Seeger Sessions" stuff, early American blues musicians played American folk music and if you want to listen to their roots you're going back to field hollers on the one hand and bluegrass on the other. I love the blues but I wouldn't class myself as a fan of bluegrass but without one there wouldn't be the other.
Wise words indeed.
