I never thought I'd like listening to folk music, but the music in this movie (composed by Dave Van Ronk, a real folk singer) was really enjoyable to listen to. It follows the 'nomad' life that an aspiring folk singer goes through, dealing with tons of different people and trying to make a name for himself after the passing of his musician partner. I found it frustrating to watch Llewyn stumble so much, but it added to the message of the movie.
