I'm totally one of those whiners who thnks this is silly and impossible. But, amke me pick and I'd go with a double of something most likely. When feeling all American and patriotic, I'd take the Minutemen: Doubles Nickels on the Dine...when feeling a bit more anglocentric...London Calling's as good a choice as any.

And sorry, but I don't really believe in any objective "greatest." These are just 2 albums I've played to death and always pop to the top of the stack eventually for me. And I could just as easily replaced those 2 with about 10-20 others and not feel like I made any lesser choice.
