For me memorial is best and number 1

I only agree with Wolfheart and Irreligious being so high on this list, but I disagree with basically everything else. Memorial is bottom material for me easily and Sin/Pecado is a great album that's pretty high on my list, definitely 4th place or something. Also, it's beyond me why The Butterfly Effect is BELOW Sin/Pecado while those albums are very similar in style except that Sin/Pecado is much, much better. And honestly I don't like the fact that you've listed a few other releases of them too, because why not include The Great Silver Eye or Serpent Angel while you're at it?
