Any opinion expressed on this is likely to hinge on whether you like Dylan or not. I dislike Dylan for some of the reasons Dick gives (deliberate and self-serving obscurantism, a whiny voice and, one of my own, his awful harmonica use), but, as for nicking from the "tradition," to me that's an illegitimate criticism. First, it's a free country. Second, you don't have to listen. Third, any tradition worth its salt, with a strong heart and soul, can easily shrug such incursions off. Classical music can easily shrug off the Swingle Singers and the Royal Phil jazzing up a few classics and the Three Tenors murdering Nessun Dorma......
