*SS is right about this; it is a matter of degree, and to some** extent it is all folk music.
**More precisely, to a very, very limited extent.

It's not a matter of degree at all, it's a matter of Traditional Songs and Folk Songs being two completely different things which is what all the available evidence suggests. What we really need here is what Wiki calls disambiguation - because according to you guys most of what happens in the name of folk these days isn't folk at all. Now that just can't be right - or can it?
