Jackie's composer is Mica Levi, I'm a fan of her work in Under the Skin. I haven't seen Jackie yet, but I enjoyed La La Land's soundtrack. As for the Oscars, I'd be glad if Casey Affleck and Mahershala Ali got their awards, because I thoroughly enjoyed their performances - however, there's so much I haven't seen that I don't have an opinion on who should win. From the films I watched, I preferred Manchester by the Sea's plot, but I felt La La Land and Moonlight were better directed.
