While some are surprised Bob Dylan won the Nobel Prize in literature, Sean Wilentz isn't

Princeton University professor and historian Sean Wilentz says that Dylan fits right in with that crowd. Wilentz, the author of the book Bob Dylan In America, joined NPR's Audie Cornish to discuss the news.

I mean, Dylan's relationship to prizes — to authority in general — is, shall we say, cagey.
