why do i get the feeling i've seen that set many times before?

right here comes my one big complaint!

IF the band are really intent on doing this acoustic format why not really throw the set around a little because it being stripped down raw to just acoustic guitars, percussion etc allows for them to mess with the set... all they need is a rough idea of ANY song they want to play and a lyrics sheet to remind jon if he's stuck

why do we get roughly the same 7 or 8 acoustic songs continuously... and let's face it the electric set for these format of shows is only changing by maybe one song at a time
