As AH.com's self-declared Dylan expert (kidding...kinda), I'd say ASB. Dylan didn't want to be a songwriter, ironically. He was focused on fame from the beginning. While groups like The Weavers were in their prime and the folk scene on Greenwich Village was starting to move towards it's early 60s's climax, Dylan was rocking and rolling to Little Richard and even once hitchiked to South Dakota to play with Bobby Vee. While he was always a folk fan as well (I mean, he literally stalked Woody Guthrie when he got to New York), I think Dylan was more interested in fame then he was in writing, poetry, politics, religion, or philosophy. It just so happened that his incredible song-writing talents came to be the vehicle to propel him to that fame.
