Kid A was interesting, but Amnesiac and HTTT were both simply phenomenal IMO because they each seemed to have in their own way, at-least from my point of view, a little more variety and cohesion respectively. Kid A is still a fine album though....
Also, just so you guys know, I don't consider interludish stuff to be filler on any album once it goes past the 1:30 mark, so none of that **** when you talk about HTTT.
