I think the difference is that Leonard it a true poet, of the first water. Dylan seems to have been a flash in the pan, not a one hit wonder by any strectch but isn't it funny how we loose the light little by little and the days grind by til the 'danes* take us down or until we just forget those creative fires and how they felt.

Cohen always had a maturity to his works that is missing in many of the others. I think that is what gives it a timeless quality, as relevant today as when we first heard them. I think in Mr. Cohen's case you could genuinely apply the word genius without fear of being overly enthusiastic of exuberant. He fits the definition. He always has.

*the Mundanes, that is!
