The Nobel Prize in Literature for 2016 went to Bob Dylan "for having created new poetic expressions within the great American song tradition". From the New York Times:
Sara Danius, a literary scholar and the permanent secretary of the 18-member Swedish Academy, which awards the prize, called Mr. Dylan “a great poet in the English-speaking tradition” and compared him to Homer and Sappho, whose work was delivered orally. Asked if the decision to award the prize to a musician signaled a broadening in the definition of literature, Ms. Danius jokingly responded, “The times they are a changing, perhaps,” referencing one of Mr. Dylan’s songs.
