Rosalia’s highly anticipated collaboration with Billie Eilish is an unforgettable feat…

The 27-year-old Spanish singer-songwriter released “Lo Vas a Olvidar” on Friday, featuring Eilish singing in Spanish.

With dreamlike, almost hazy melodies, the slow-tempo, bilingual song brings to the forefront Eilish and Rosalia’s vocal chemistry and enchanting harmonies.

“Dime si me echas de meno’ aún,” Rosalia kicks off. “Dime si no me perdonas aún,” continues Eilish.

The two artists go back and forth on the melancholic lyrics before Eilish closes off with a thought-provoking verse in English: “If I wasn’t important, then why would you waste all your poison?”

The official music video, filmed by award-winning director Nabil, shows the two artists’ powerful performances in a somber setting.

The video has already garnered more than 20 million views since its release.
