Maybe it's time to add a couple more Nobel categories--cinema and music. In music we could have had Miles, Trane, Ellington, etc.
The literature prize has always been the odd one out among the Nobels.
As for Dylan, I remember finding a book of his complete lyrics back in 1978. At the time I had not heard much Dylan, but I read through just about all those lyrics--and they were, for the most part, fascinating. As a songwriter/poet, they don't come any better than Bob.
