4. Bob Dylan, 'The Times They Are A-Changin''
Bob Dylan's old friend Tony Glover tells an amazing story about finding a draft of "The Times They Are A-Changin'" in a typewriter: "I said to him, 'What is this shit, man?' And he responded, 'Well, you know, it seems to be what the people like to hear.'" Whether or not Dylan really wrote the protest anthem in a moment of cynicism, it remains one of the defining works of the 1960s. It was released weeks after JFK's death and just a few months before the Civil Rights Act of 1964 passed. It was a time of tectonic cultural shifts, and Dylan summed it up in a three-minute folk song.
