The debate over "best" album in rock history seems to not be terribly vituperative. Craig Shaw Gardner floated the soundtrack to Saturday Night Fever under the "best representative of the zeitgeist of its time" and I can't really disagree with that. That's the criteria by which I rank Nevermind and London Calling highly as well. If I had to start from scratch this instant, I think being a music historian and critic would be a good career for me. And my pick for best album of all time under the "when I hear it I feel in tune with the notion that anything in this world is possible and am uplifted by the sound" category would have to be Coltrane's Love Supreme.
