Is Pink Floyd's Dark Side of The Moon the greatest album of all time?

Groundbreaking? Alright. Revolutionary? Sure. But is Pink Floyd's Dark Side of the Moon really the greatest album of all time? Some would scream, "Yes" and others would cry "No." Listening to this album is a rite of passage for anyone who calls himself or herself a fan of Rock and Roll. G.O.A.T? What do you think?
