Sorry, Guest. My opinion is that, we can't "let the kids alone".
I'm not a teacher, or anywhere in the teaching profession. However, I enjoy the folk music, having grown up with it.
Many of today's kids, and even their teachers have not. We need to be able to inoculate these generations in some "real" music, rather than pop ONLY. Not saying Pop is bad, but if people grow up thinking that is the ONLY kind of music worth listening to, well, they'll be sadder in the long run, and so will we.
