I personally think it's a really good set. I really can't figure out why are people still surprised about the shortened songs stuff. We all knew it was gonna come back after the European tour, though it's kind of weird to see a new song like UIG shortened. IMO, the Ballad Medley is really not that bad. After watching a couple of shows from the European tour, I believe this kind of set definitely works. It seems like the crowd is having a lot of fun, and so does the band. Playing the shortened songs gives them the opportunity to play songs that wouldn't make it to a set today in any other form (Blackout, Robot Boy...). I personally think it's great that they decided to do something different and new. Maybe it's just me, but I really like the whole idea of medleys, mashups and solos.
On another note, the Rebellion clips sound great. I really can't wait to hear the full song live.
