I SO hope U2 doesn't tease us with more "never before heard" live songs that every fan that cares has probably already heard from various places.
I want to be optimistic and hope it's new album news or even some random new U2 song. (Finish North Star!) Wasn't there a rumor saying they were hoping to release an album in January 2013?
I read about the Tiesto collaboration before and while I'm interested in hearing it, I'm cringing that it's a re-mix of Pride. Seriously?! There are just some songs that shouldn't be "re-mixed". -- Tiesto is awesome, but I hope the special news tomorrow isn't that.
