"To use a term such as "folk music" is perfectly acceptable to me if it includes music from the Balkans, Italy, Spain, China, Nigeria and other countries of the world - and the various regions and traditions in each."

Just to clarify the point I was trying to make here:

People have used the example of going into a store and looking for a CD under "folk music" and having an idea of what it contains. My point is that there are so many traditions at play that two words cannot give an accurate description, rendering that argument pointless.
