“Bellyache” by Billie Eilish

"Bellyache" was the second single from Billie Eilish's debut EP, dont smile at me, released on February 24, 2017 through Darkroom and Interscope, and it's a murder confession dressed as a sunny bop. She wrote it with Finneas O'Connell, who produced and recorded it, and Rob Kinelski mixed. The groove is midtempo alternative hip-hop and electropop, shot through with deep house, R&B and a Latin, macabre streak, and Eilish sings it from inside the head of a psychopathic killer, which makes the easy lilt all the creepier.

The video puts her in head-to-toe yellow, tossing dollar bills and dancing down a highway. It never cracked the Hot 100 but peaked at three on the Bubbling Under chart and lingered there for 32 non-consecutive weeks, and she kept it in her live sets through her 2019, 2020 and 2022 tours.
