I thought I'd get a flurry. I tend to agree with the notion that "traditional" music is something passed down. In fact, when I studied music in college the definition of Folk Music was not only defined as traditional, but it's origins were hazy at best. Especially where the subject of author or composer were concerned. Then comes the 20th century. If we adhere to the TRADITIONAL definition as taught in music history books, then Woody's and Leadbelly's songs aren't folk music either.

Hence my point. Many artist write and/or perform music that is strongly influenced by traditional folk music(music history definition) and have achieved commercial success, allowing their songs to be sung by millions(reference to Bert's definition). These are folk STYLE musicians (Dylan included) whether we like it or not.

If you want to differentiate by attaching the "TRADITIONAL" label, that's fine. We always have to categorize. That's the way we are.
