yes they do...in jazz forums, in country music forums, blues forums.

there are no end of the people who want to pooh pooh original creative effort.

god knows why...the more people they exclude, the less chance people will have in hearing their own style of music, either alluded to as a source, or performed.

when folk, blues, jazz etc., as we know it,   is safely stuffed into ghetto like classrooms , museums and college courses. i suppose ordinary folk will have to beat on dustbins or yell in canyons. but at least it will be folk music.
