World conditions make this year’s Grammy voter choices in the visual-media categories somewhat harder to predict, in part because so many of us have been staying home watching television. So while some score nominees are likely to come from late-2019 releases, including Hildur Guðnadóttir’s Oscar-winning “Joker,” John Williams’ “StarWars: The Rise of Skywalker,” Thomas Newman’s “1917,” Randy Newman’s “Marriage Story” and Alexandre Desplat’s “Little Women”), final choices could easily include streaming content which, while eligible, has rarely made the nominations list.
