At the end of the day there is not much point getting worked up about contemporary folk boundaries. One man's poison is another man's poisson.
Once, apart from limited radio and TV exposure attendance at a folk club was the only comprehensive way of enjoying/learning........ the genre. Instruments are far more widely available today(personal observation-could be wrong), young people have many more means of obtaining exposure to different genres and I suspect boundaries are far more fluid. Some people simply like the music/songs. To like it does not mean you have to research the origins of the music to the nth degree. Some do, some don't. even when they do, some get it entirely wrong. I remember reading a thread about "Farewell, Farewell" where heated arguments arose over the songs origins.(We all know who wrote it)

We are fed this bucolic idea of how traditional music arose amid the hoary sons of the soil and transmogrified over county and country boundaries into a totally different beast. This mutilation over time and space seems to be inherent in the definition of traditional Folk.
I would ask how the same process can possibly occur in the modern age with instant, accurate electronic capture and transmittal.
Of course that dirty word commercial and perhaps copyright hangs over the modern scene like a dark stifling cloud according to some. The fact is that it represents the modern world. Very few can afford to work without payment. Is not composition work, and worthy of reward?
Is entertainment not worthy of having a price set on it?
