Normally, I don't give much to the opinion of music magazines, but as far as I remember The Rolling Stone chose „London Calling“ as best album of the 80ies - even if it was published in December 1979. And in this case, I have to agree with TRS.
There‘s no bad or even mediocre song on it, only classics, political and poetic - and of course the best bass line ever: The Guns of Brixton
