I keep listening to the music from the score and I honestly think that it is a very good score. It suits the movie perfectly. The first track:
"They'll Remember You" fits the fact that Stauffenberg died a hero and all the men in the plan are all hereos. The movie is really good and the whole story itself is too good to be true that 700 people were involved with the whole operation and they got so close to secceding in the plan. In a way, to me, its kinda sad a bit. The first track on the score gives you that emotional feeling to it. There is another track on the official site similar to that track, and without the choir and it sounds even better than the original.

I've listened to other John Ottman soundtracks and I love each one. I don't know about anyone else, but I think his music works so well for the movie.
