Read the excerpt from A Short Account of the Destruction of the Indies. And this also is as really true. . . . the very Tyrants and cruel Murderers cannot deny without the stigma of a lye. . . . the Spaniards never received any injury from the Indians, but that they rather reverenced them as Persons descended from Heaven, until that they were compelled to take up Arms, provoked thereunto by repeated Injuries, violent Torments, and injust Butcheries.

–A Short Account of the Destruction of the Indies,
Bartolomé de Las Casas, 1542

explanation:

dylan has written many enduring songs and he has received several awards for his musical achievement;  

any written work with artistic value can be considered literature; especially if such work is publicly recognized, and has had importance and endurance among people; whether is poetry or fiction or drama or even criticism, since it's the transcendence and representation of a culture, language or people in a period of time to more people, using letters (words), regardless the subject.

the nobel prize in literature is given to authors from any country based on a body of work as a whole that inspires and nurses the life of humanity.  

and the work of bob dylan matches that description, therefore is well deserved since he'd created new poetic expressions within the american song tradition, that has inspired and influenced the lives of many people, not only withing the united stated but worldwide as well.
