I said those recordings didn't make the final cut of Kid A, which is the truth. I didn't describe them in the derogatory terms of being "leftovers". With that said, some of the Amnesiac songs could well be called leftovers, whereas others (like Pyramid Song) are the sort of tracks that were so good they would clearly have appeared on some later album even if Amnesiac was never made.
Or maybe I have listened enough and didn't like it as much as you do! Oh no, I forgot, that's impossible...
That is an unpopular opinion, though anybody who disagrees with it is clearly idiotic. And this has nothing to do with liking or hating Tool; it makes no sense from any standpoint to say that Aenima is in any way a superior piece to Lateralus.
