Not to worried about what it is Amos. I often use "If it sounds like folk to me, it is". I do think though that whatever definitions we use, we all have some idea of the "ballpark" - it's just that some definitions are narrower than others...

Fortunately, most of us are open enough to at least agree to dissagree with the ideas of others without the need to try to legislate for what makes it, or the singers of it real.
