Rosalía

A Spanish collaborator who joined Billie Eilish for the Euphoria soundtrack single "Lo Vas a Olvidar" in early 2021.

Rosalía is a Spanish singer-songwriter who collaborated with Billie Eilish on the single "Lo Vas a Olvidar." Released from late 2019 to early 2021 as part of a series of commercially successful singles by Eilish, this track marked a specific turning point in her discography. Unlike her usual work co-written and produced with her brother Finneas O'Connell, this song was a joint effort with Rosalía for the television series Euphoria.

Lore & Background

The collaboration between Billie Eilish and Rosalía resulted in the song "Lo Vas a Olvidar," which was released as part of Eilish's run of singles from late 2019 to early 2021. While Eilish has co-written almost every other song in her discography with her brother Finneas, this track was explicitly noted as a collaboration with Rosalía for the television series Euphoria. The song appeared during a prolific period for Eilish that also included releases like "Everything I Wanted," "No Time to Die," "My Future," and "Therefore I Am." This partnership highlighted Eilish's ability to bridge genres, following her earlier work on soundtracks such as "Bored" for 13 Reasons Why. The release of "Lo Vas a Olvidar" demonstrated that while Finneas remains the primary producer and co-writer for Eilish's main studio albums like When We All Fall Asleep, Where Do We Go? and Happier Than Ever, she is willing to explore distinct sonic territories with other artists for specific projects.

Reader's Guide

To understand Rosalía's role in Billie Eilish's career, one must look strictly at the release of "Lo Vas a Olvidar." This single was released from late 2019 to early 2021. It is categorized as a collaboration with Rosalía specifically for the television series Euphoria. While Eilish's debut album When We All Fall Asleep, Where Do We Go? (March 2019) and her second album Happier Than Ever (July 30, 2021) were primarily written and produced with Finneas O'Connell, "Lo Vas a Olvidar" represents a distinct collaborative effort. Fans should note that this song is separate from Eilish's other soundtrack hits like "Bored" (2017) or "Lovely" (2018). The track stands as a unique entry in her discography where the primary co-writing credit shifts away from her brother to include Rosalía, marking it as a special project tied directly to the Euphoria franchise.
