I'll definitely be joining in on the setlist parties once my show is over.
I just found that as much as I loved the shows I went to on the last leg, I pretty much always knew which song was coming up next, since my shows were the last ones on the leg. I love the element of surprise, and think I'll have a much better experience not being as familiar with the setlists.
I may have to unfollow some U2 people on Twitter for a week or two, or somehow just ignore their tweets.
I'm on that site constantly, so we'll see how well that goes. I wonder if there's an app or special site that I can download, where I can ignore them for a while but not completely delete them from my follow list?
