Yeah, I seriously listened to that album about 50 times before I heard it, sometimes with headphones. I was never looking for it and never knew where it happened, though (someone told me it happened in the Moonlapse Vertigo intro, which it doesn't, so I was only trying to hear it there). I don't blame you for not wanting to go looking for it, though I bet I will stop noticing it after a while anyway (like the first several times I listened to April Ethereal the clipping on the cymbals in parts distracted the hell out of me but I don't even notice it anymore).
