But there certainly can be quite a high degree of cliquery to be found in many music circles which eschews the work of successful artists, seemingly purely because they incidentally happen to be successful.

I can't speak of the rest of musical circles.

I haven't met many of these people. Having been involved in folk music of one sort or another for well over forty years and most people I have an awareness of the struggle it is to make any kind of living in any kind of music.

Most people are delighted when some people are seen as commercially succesful.

Of course there are some nutters around who will shout and bawl about people "selling out" or whatever.

But most people see them as irrelevant. And very often their perception is wrong anyway.
