You can pretty much follow the entire plot line of the film, including the locations, based on this tracklist.

Track 17 being titled "Your Father Would Be Proud" looks like a spoiler for the death of Galen Erso. Reminds me of "Qui-Gon's Noble End" from The Phantom Menace soundtrack. Not as big of a shocker since I would expect Galen to get killed, but still. It comes at a point in the soundtrack when it may actually be Jyn's death - I think it's the climax to the film.

The last three tracks are listed as suites. I think they will play during the end credits. In the John Williams Star Wars soundtracks there would always be an ending theme that is played directly following the last scene of the film as one track. For example, "The Throne Room/End Title" from A New Hope.That end title track always had a medley arrangement of all the major themes from that film. But with this not being saga film and not doing things exactly the same way, maybe those three suites ARE the ending credits medley, as separate tracks.

That would mean track 17 may be the climax of the film:
17 Your Father Would Be Proud (From "Rogue One: A Star Wars Story"/Score)

And Track 18 may be the final scene.
18 Hope (From "Rogue One: A Star Wars Story"/Score)

That would make perfect sense, because "Hope" leads directly into "A New Hope" the same way as the ROTS soundtrack ended with "A New Hope/End Credits".

That "Hope" track might play as Leia receives the transmission from the Rogue One crew while she is on the Tantive IV.

And yes, I'm both a music nerd and a Star Wars nerd.
