#music festivals

i was at a festival last weekend and i totally misjudged the setlist for one of my favorite bands. i was so convinced they'd play this one song that's like their biggest hit, but nope. they didn't even touch it. and to make matters worse, i was ranting to my friends about how they always play it and it's their best song... yeah. i felt pretty dumb when they just skipped right over it. has anyone else ever been so sure about a setlist only to be totally wrong?
