The fact that Bob Dylan was awarded a Nobel Prize was very controversial among the public. However, I believe that this award was justified.
Those who disagree with the decision argue that songs are not usually considered literature, and that the prize should only take into account works such as novels, short stories, poems and essays. Others have argued that, while influential, Dylan's songs do not have the quality that is often expected from a Nobel Prize winner.
However, I believe there are enough arguments to justify this decision. First, Dylan's songs are very complex and rich. They use a wide vocabulary and literary devices that are commonly found in works of great quality. Moreover, Dylan references many other works of great writers, such as Ezra Pound, Arthur Rimbaud and Paul Verlaine. This places his work in the literary canon. Finally, Dylan's lyrics have been very influential in cultural, literary and artistic circles. All of this justifies the committee's decision to award him the Nobel Prize.
