"Musical" and "snobbery" don't go together. A musician is open to anything rather than to condemn it because it doesn't fit that musician's framework.

I mentioned before that I don't like Schoenberg and the Twelve Tone theory of music but I would be the last person to say that Schoenberg wasn't a great musician.

I feel that way about some forms of heavy metal, rock and roll in general and rap.
There is value in every music and that is why it's produced.

I have preferences as most do but the condemnation of a musical style generally makes no sense to me.   

The attitude of "snobbery" coming from folkies, which I have encountered, is a form of ignorance about music in general. The only way to really appreciate folk music, jazz or so-called "classical" is to look at the big picture of music and see how each style fits in.
