Billie Eilish, who cleaned up at the Grammys, leads the pack with seven nominations.Lizzo and Lil Nas X, who are up for six awards each, could give Billie some serious competition for Song of the Year, the one category where all three go head to head. Other big names receiving multiple nominations include Shawn Mendes, Ariana Grande, Halsey, BTS, The Jonas Brothers and Taylor Swift.
