Parts 0.00-0.30 and 9:29-9.59 mainly, there's some good stuff in the middle also, but less soundtrackish imo.
Would fit Skyrim perfectly... of course needs alot of remixing
But it would be sweet.

Great flute. Main theme needs to be more powerful of course, but this kind of stuff needs to be in too, especially with regional/seasonal playlists. Or, maybe the towns/castles have actual musicians doing that stuff now and then. You could keep the vocals in that case, and the music can be merry and fast.
