"Bellyache" is a song by American singer and songwriter Billie Eilish. The song was released on February 24, 2017, through Darkroom and Interscope Records. It was written by Eilish and Finneas O'Connell, with the production being handled by O'Connell.
Mike Wass of Idolator called it a "sinister synth-anthem that positively seethes fury and frustration". Billboard's Jason Lipshutz said "she wrapped the macabre lyrics around a delectable pre-chorus hook and a steady acoustic pattern that eventually gives way to a sizzling drum machine. She knows that a song like 'bellyache' is going to get her more sideways glances than Top 40 airplay, and that's fine with her." Pigeons and Planes's Jacob Moore stated that the song "shows off an intriguing edge, which is in large part due to the fact that this is a song about murder".File Hashes
