"Lo Vas a Olvidar" pairs U.S.-based Eilish with Barcelona-born Spanish star Rosalía. It's Eilish's first cross-national collaboration to hit the global charts, and Rosalía's fourth. The latter's previous team-ups aligned her with Travis Scott (from the U.S.) on "TKN"; Bad Bunny (Puerto Rico) on "La Noche de Anoche"; and Sech (Panama), J Balvin (Colombia), Daddy Yankee and Farruko (both from Puerto Rico) on "Relación," which is, notably, the only song to hit either global chart so far by artists from four distinct territories.
Still, a global chart hit by artists from two or more territories is not all that unique. This week's Global 200 sports 40 such songs, or 20% of the entire chart, three of which are by Rosalía. It is rarer to see chart hits that mix languages, like "Lo Vas a Olvidar." Eilish and Rosalía both sing lyrics in English and Spanish, making the track one of only 11 multilingual songs on the latest Global Excl. U.S. chart and one of just seven on the Global 200 (or 3.5%).
Three multilingual songs have topped the global surveys so far. "Hawái" by Maluma and The Weekend (Spanish and English) led the inaugural Global Excl. U.S. chart (Sept. 19), while Blackpink's "Lovesick Girls" (Korean and English) topped the Oct. 17-dated list. On the Global 200, Jawsh 685, Jason Derulo and BTS led the Oct. 17 chart with "Savage Love (Laxed – Siren Beat)" (English and Korean).
Further, global chart entries by Niziu and Dua Lipa (featuring Angele) have mixed English with Japanese and French lyrics, respectively.
Those hits, including "Lo Vas a Olvidar," reflect multilingual and multicultural collaboration, as well as another shared element: English lyrics. Even rarer than a multilingual song on the global charts is a multilingual song on the global charts that mixes two languages that are not English. In fact, only one song has done so in 2021 so far: "Djadja," by Aya Nakamura featuring Maluma, with lyrics in French and Spanish, spent a week at No. 198 on the Global Excl. U.S. chart, after it reached No. 32 in September.
Back stateside, "Lo Vas a Olvidar" surges from its No. 45 debut to No. 3 on Billboard's U.S.-based Hot Latin Songs chart following its first full tracking week. It's the biggest-selling Latin song of the week in the U.S. (3,000 downloads) and the second-most-streamed Latin title (8.2 million), behind Bad Bunny and Jhay Cortez' "Dakiti." Reflecting the same metrics, the track bounds 48-6 on Hot Rock & Alternative Songs (and debuts at No. 62 on the all-genre Billboard Hot 100).
The partnership has earned Eilish her first entry on any Billboard Latin chart, while Rosalía clocks her fourth Hot Latin Songs top 10, all notched consecutively since June.
