I think we can rule out Hit the Floor, Nobody's Listening and Session. Nobody really seemed to care about Don't Stay when they played it in 07-08. If you ask me, it's just a poor man's One Step Closer. From the Inside wouldn't really be special since they just recently dropped it. So, I agree with what the others have said: Figure.09, the fan favorite or Easier to Run. A piano/acoustic version seems more likely to me than the album version, though.
