Rogue One Hope track has hidden Imperial March theme

The latest Star Wars so-nerdy-its-cool news: People have figured out that the Rogue One soundtrack contains a really neat "hidden" reference to the Imperial March (which some people think of as Darth Vader's theme). Although the official Imperial March is included at the end of the film -- right as you're thinking "I can't believe I just saw that" -- it is also "hidden" in the track playing just before that, when Darth Vader is busy making the best ending of a movie ever. This video plays the track called "Hope", then doubles the speed of playback, then overlays it with the Imperial March. Nerdy sleuthing! :)
