Billie Eilish: Bury a Friend (2019)

The perfect modern Halloween anthem. With its whispered vocals, distorted beats and horror-inspired video, Bury a Friend cemented Billie Eilish as pop’s queen of the macabre. NME described it as “dark pop perfection” — the sound of nightmares made chart-worthy.

Billie said: “It’s literally from the perspective of the monster under your bed. That’s the fear — and the fun — of it.”
