The original Glory song (like on Radio or YouTube) contains a cool rap part performed by Common, that is not featured anywhere on this score. But as far as I discussed with my fellow-music-enthusiasts, most of them actually go for the piano score itself, correct chord progression and the pleasant choral suggestion, which is all present in this arrangement. This version perfects suits a good soloist, though. As for me, I would still write in the rap parts somehow to make it totally complete and nice.
