I don't think at all there is a requirement for folk music to be listened to for its content. At least I never heard of such a rule and I am sure I would have by now. Half the time I don't have an idea of what a song is about and the other half I have a vague feeling it is about a coal mine disaster or a shipwreck or global warming but don't really harken to the details unless I see the words in print usually. But that doesn't stop me from enjoying the music..oh bad word..enjoyment...mg
