Has nobody (recent) got the point?

"Folk" does not mean "good". It does however refer to music having certain definable (with difficulty) attributes. It is precisely to avoid excluding music that is not "folk" from what we do that a correct nomenclature is needed.

Reggae is not a waltz, and klezmer music is not played by the Black Dyke Mills Brass Band.

Apart from those who are determinedly of recto-cranial insertion, it is understood that the expresion "folk" of a type of music has meaning, and amongst those who bother to think there is not a huge difference about the core of that meaning - although the fringes are another question.

So let's formulate a name for the other stuff. It is unnecssary and frankly obfuscatory to take an existing term and seek to corrupt its meaning, and of no value to do so out of laziness and sloppiness.

I play plenty of faux-folk, and much of it I like as well as folk. But that doesn't make a dalmation a leopard even thought they both have spots.

Stupidity is one thing. Intentional stupidity is worse.
