I loathe their cover of Like a Rolling Stone. One of the fantastic things about the original is that all the instruments blend into a cohesive whole but you can pick out one thread in particular and listen to it in isolation as it does its thing for the whole song--the liquid organ riff, the piano, the lead guitar, bass, rhythm guitar, Bob's voice. In Green Day's cover the whole thing is just utterly buried under a wave of guitar. Also, let's face it, Billie is better than Dylan technically when it comes to vocals but he can't come close to the passion Dylan put into his vocals on this particular song.
