Rosalía

Verified Timeline

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.

In Their Own Story

The narrative of this collaboration centers on the release of "Lo Vas a Olvidar" in early 2021. During a period where Eilish was releasing multiple commercially successful singles leading up to her second studio album, Happier Than Ever (released July 30, 2021), she partnered with Rosalía for this specific track. The song served as a soundtrack addition for the television series Euphoria. This event occurred between the release of "Therefore I Am" and Eilish's third studio album, Hit Me Hard and Soft (released May 17, 2024). Unlike her debut EP Don't Smile at Me or her first two albums which were written alongside Finneas O'Connell, this project stood out as a dedicated collaboration. The song joined other soundtrack appearances in Eilish's history, such as "Ocean Eyes" on Everything, Everything and "Lovely" (with Khalid) on 13 Reasons Why: Season 2.

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.
