One of the fascinating things is the "drift" in folk music over the years.
Remember, Folk Music, is music of the people. Reggae, Hip-Hop, and Rap are all valid expressions of A people. We may not appreciate some of the subtle aspects of some kinds of music (I don't listen to a lot of classical), but that doesn't negate the interest many others do have for that kind of music.
While I tend to agree that many "pop" songs are lacking something, that doesn't hold for every piece of pop music. Some of it is excellent poetry.
As stated above, I find that many "purists" tend to close out other types of music. While I enjoy the traditional forms of music from my region (Eastern Canada), I would find other regional music excellent for various reasons.
There is no reason we can't be "open" to others' interest in music. Might have something to show us.
Wonder if this thread should have a BS: in front of it.
