I agree that this a rather crude method of deciding popularity...perhaps it is a better measure of notoriety. But I thought it would make an interesting change from the debates along the lines "I like Kate Rusby better" "Oh. no, I like Eliza Carthy better".It also avoids any inconvenient discussion what is, or is not, folk music. There are more threads here devoted to Dylan than anyone else(that I have discovered, anyway). Quite a few more than my own outfit the Boat Band, anway, we only only have one thread. But then, quality not quantity, that's what I always say.
