“The story of Like A Rolling Stone is a story of creative insight. It took only a few seconds before a mental block became a work of art. In a 1966 interview with Playboy, Dylan assessed the impact of the sudden breakthrough on his music. "Last spring, I guess I was going to quit singing," he said. "But Like A Rolling Stone changed it all: I didn't care any more about writing books or poems or whatever. I mean, here was something that I myself could dig."”
