Actually, wwallinga, I totally agree with you. That said, I suppose I did facilitate that sort of spoiling by posting the setlist in another topic, but it was, after all, at topic specifically about a concert which had just finished. In any event, though, seeing the setlist before going to the concert just feels to me like finding out as a kid what all of your Christmas presents are before the morning actually dawns. It just kills a lot of the surprise... not to mention the suspense that comes when they intentionally drag out announcing which song they're about to play.
To each his own, I suppose, though.
