Don't be so ready with the white bread and nostalgia characterizations. That stuff was as revolutionary in its day Dylan was in his, and the genius behind does not diminish down the ages.
Here's a companion thought though. The modern world is so obsessed with breaking down convention and creating revolutions, that it tends to hold contempt for the old as a matter of principle. The drive to be cutting edge supercedes the drive to create beauty. Yet in our hearts the yearning is for the latter, and in the end we can't help but return to it.
I have several music fantasies, but by far the most prevalent is the desire to be able to travel in time, so I could take samples of different kinds of music to great musicians of the past and get their impression of it. To play Ellington to Motzart or Monk to Beethoven.
