"I mean, if you look at the objectives of The International Council for Traditional Music (formerly The International Folk Music Council) which are: to further the study, practice, documentation, preservation and dissemination of traditional music, including folk, popular, classical and urban music, and dance of all countries. I think that just about covers it!"

What it covers is an attempt to dilute the definition to suit contemporary audiences.
I don't know anything about the International Council for Traditional Music but its
goals are amorphous and I don't think they cover it at all. I can see that they might want to preserve some commercial music and some classical but it ain't folk and never will be.
Popular music is music industry driven. Classical music is academy trained music. Urban music is a sub-genre of pop.

There is a tradition in the commercially-based popular music field but it ain't folk.
It's money-driven whether we like it or not.

Classical music is a tradition but it ain't folk. You learn that in music school, pure and simple.

Just because you like certain forms of music, that doesn't mean it qualifies as folk music.
