Capping off 2019 was no easy feat for these artists. They pushed boundaries, blended genres, broke all-time Billboard Hot 100 records and gained incredible streaming numbers.
For starters, Lil Nas X did all of the above this year. The rapper expertly fused hip-hop and country to create the No. 1 banger "Old Town Road" with Nashville vet Billy Ray Cyrus -- which rode for a record-breaking 19 weeks atop the Hot 100.
Lizzo and Billie Eilish both secured nominations in the Big Four Grammy categories: album of the year, record of the year, song of the year and best new artist. Lizzo scored for the deluxe edition of her third studio album Cuz I Love You, while Eilish's album of the year nod went to her debut LP When We All Fall Asleep, Where Do We Go?
