Or maybe because of it. That song first made me think of him as a writer as well as a singer. It doesn't surprise me that Dylan is hailed as a Great American Poet. He draws on a long tradition and speaks in a voice that is both Appalachian and urbane. He writes for all of America, and writes well.
Few people disagree.
For me, however, no particular song is the best. It is the totality of his songs that amazes me, the way that taken all together they seem to cover everything that has ever been American. I'm working on a film about tattoos. Despite advice from many authority figures, I am considering getting one. The film, which covers both getting tattoos and getting tattoos removed, is helping me decide.
