I'm sorry you disagree Don, but I feel that contemporary society has already changed the definition of folk music - and the change can be traced back to the early days of the folk revival of the 1940's.   It does NOT include ANYTHING "they" want to include. It is more than just a "FEW" members of contemporary society who have worked to recognize the change. I think if you look hard enough, you will see that most people are comfortable with the way the words have evolved.

You are right though, because basically the definition remains unchanged - it just has a much broader interpretation than you wish to attribute to it.
