I watched The Hateful Eight movie and i love the soundtrack of this film. The soundtrack is such a phenomenonal music that you feel like you're in that movie. Because of that in the category of ''Music Original Score'' Ennio Moricone(The Hateful Eight) will win. And here's a little information of him:

He is well known for composing the scores to Western movies, particularly Spaghetti Westerns. In 2007 he received the ''Honorary Academy Award'' for his many great movie scores.
