Great albums (can vouch for the Beatles, Nirvana, and Zeppelin ones anyways). But did you have the United Kingdom filter turned on or is this just a British website o_O ? (yes I know Nirvana isn't British but the list favors British bands as a whole). But really though, solid list.
And I suppose this is only best Rock band albums? If an aggregate list of top albums doesn't include Michael Jackson's Thriller (love him or hate him), I'd question it. I suppose these are the faults of crowd-sourcing. IMDB's top 250 is another good example. The Avengers #59 above A Clockwork Orange or any other dozens of movies on that list? Yikes.
