Although I have read recently some lengthy academic papers That go into the history of how the word 'folk' was evolved to be attached to lore/tales/music/dance/song, and they try to claim with some success the terminology is heavily flawed, I think everyone here knows that whatever their limitations are they are real and can and are applied to a specific body of material. My only get out clause is that I don't accept that the boundaries are as rigid as some would have it.
