i've never got Nevermind personally, it's good but not the 3rd greatest album of all-time. In Utero is much better. I've never got punk either so London Calling and NMTB i don't like. Sgt Peppers is way overated and definatly shouldn't be in the top 50. Revolver is great though
The best album i've ever heard is Neutral milk Hotel's In The Aeroplane Over The Sea, which currently sits at #623, and OK COmputer is my 2nd fabvourite and that's currently #14 and Loveless should be way higher than #77
