But I don't think it is so good to get one rare song out of twenty.. There should be some base list like 10 to 15 songs but those other 10 should be something different... Why can't they do that, they've been playing that same setlist since Crush tour and added few new songs from releashed album. Something rare and big time please!
Tons of options:

Shot Trought The Heart,
Hardest Part Is The Night,
Wild Is The Wind,
Stick To Your Guns,
I Believe,
I Want You,
If I Was Your Mother,
Mystery Train,
Save The World,
She's Mystery,
Undivided,
The Distance,
Love Me Back To Life,
I Am,
and every song from These Days!
