I was very pleased that Adywan added the Emperor's Theme to the meetingin ANH:R, and I hope he's added it to the hologram scene in ESB:R, if just so that the Emperor's eventual arrival in ROTJ:R, accompanied by a full blast of the Theme, has been well foreshadowed by the leitmotif throughout the trilogy. And that was some run-on sentence.
Plus IMO next to the Imperial March and Force Theme, it's the coolest theme music in the series :P.
