Folk music is about the concerns of THE PEOPLE! so, the fact that there is a lot of discussion of the concerns of the people, often informs the music. Contrary to what many Americans now think, music is not just entertainment, it is education. SOngs about mine workers, sailors, soldiers of the peoples struggles, didnt just get made up, they were germanated by people involved in and working in their class interests. I wish I could cite a good song on this subject... maybe we have served you all for a thousand years?
All the best
