I've been trying to decide this for myself. I want to be surprised, but at the same time I have nieces who are tagging along and have already been bugging me wanting to know if they'll play some of their 00s music. Me = a serious fan who will be happy with just about any setlist. Them = casual fans who will be disappointed if they don't hear songs like Beautiful Day, Elevation, Vertigo etc.
I'll probably check the first show's setlist and try to avoid those after that so I'm somewhat surprised.
