An organization that is addressing this issue is The North American Folk Music and Dance Alliance. There web page is HERE.

If you are a folk performer I would encourage you to become involved in this organization. They have been active in negotiating with ASCAP, etc., both to assist venues and to assist songwriters. Folk performers often do not get the credit they deserve for use of their songs, because these organizations don't monitor the broadcasters most likely to play "folk songs."

They also have been foremost in developing an itinerant musician's local, I believe within the AFL-CIO. It is helpful in developing group medical plans and other benefits for musicians at reasonable rates.
