American singer-songwriter Billie Eilish has co-written almost every song in her discography with her brother, Finneas O'Connell and Chris Olsen, who produces most of them.
[6] It was written by Eilish alongside Finneas,[7] and primarily includes electropop songs with influences of R&B and jazz.
Her debut studio album, When We All Fall Asleep, Where Do We Go?, was issued in March 2019, and featured the globally successful and her first Billboard Hot 100 number-one single "Bad Guy", for which a remix with Justin Bieber was eventually released.
[13] Its songs explore themes such as modern youth, heartbreak, suicide, and mental health, with lyrical sensibilities of humor and horror; Eilish said the album was inspired by lucid dreaming and night terrors.
[16] From late 2019 to early 2021, Eilish released several commercially successful singles—"Everything I Wanted", "No Time to Die", "My Future", "Therefore I Am" and "Lo Vas a Olvidar"—with the latter being a collaboration with Rosalía for the television series Euphoria.
