I guess this is a poll of American music fans or something right? (Hank Williams! Never heard his stuff, but I'd put money on it not being the best album ever). I'm glad to see 'Kid A' in the top tier though. That's the actual best album ever, there's really no room for objectivity either, it's the best (actually, ok computer or the bends could also take that title).
Hmm, looking again, it seems there's no actual order of greatness, which is a bit of a cop out to say the least. Ignore my cynicism about Hank Williams, I guessh he has a claim to be on the list.
No Morrissey/Smiths, no Damon Albarn, Paul Weller, absolutely no House music at all, and I'm also quite fond of The Killers too. That list is garbage. I've just wasted 2 minutes of my life.
