"Like a Rolling Stone," Â according to this article. Generally I hate such pronouncements as they are too subjective to be definitive. Â But I think Like a Rolling Stone is as close as you can get when talking about The Greatest Rock and Roll Song Ever. It really set the tone for the second half of the '60s, blasted folk music into a new orbit, turned Dylan into a whole new level of star, led to a 6-minute song on AM radio, and so on. Just a monumental song and it never gets old. To me it still sounds fresh.
