Not to dispute your tastes, but "derived from the tradition" is a lot like Hollywood's "based on actual events," which often implies minimal resemblance to what really happened.

We don't know much about folk music but we know what we like. (Actually, some of us know quite a lot about folk music.)

In any case, the re-enacted events, like the newly written songs, are still imitations - good, bad, or indifferent.

Um? Er? Yes. And your point is?
