If they do in fact use it, it depends on how it sounds. If its just the normal song, I assume it'll only be a quick piece thrown in. However, I think they will change it up a bit...slow it down, a capella maybe, idk what but I have a feeling that it will be distorted and thrown into the Sidious/Yoda duel, Mace duel or Anakin/Kenobi duel. I highly doubt if it stays the way it is, it'll be in for long.
