"Brillo" is a song by Colombian reggaeton singerJ Balvin in collaboration with Spanish new flamenco singerRosalía. Released on May 25, 2018, throughSony Music Latin, It is the seventh track on Balvin's fifth studio albumVibras (2018). It is written by Alejandro Ramírez, Jesús María Nieves, Marco Masis and both performers.

Rolling Stone named "Brillo" an "abstract flamenco duet" whileThe Guardian had to say that "it is an undeniably sensual track where the delicate and versatile vocals of Spanish flamenco singer Rosalía shine over a minimal background".^[1][2]Remezcla's Sara Skolnick stated "Brillo is a hypnotizing track anchored by Barcelona-based vocalist Rosalía, whose mission to“revolutionize flamenco” is articulated once again through intuitive hand claps and vocal takes that lend an airy precision in conversation with Balvin's".^[3] It was called a "potential summer hit" byVogue Magazine.^[4]

After being posted onYouTube for 72 hours, the song was streamed over 170,000 times, becoming a moderate hit for Balvin. However, the track gained special recognition in Spain after Rosalía became massively successful in the country following the release of her track "Malamente" in May 2018, the lead single of her Latin Grammy Award-winning albumEl Mal Querer. The track had over 60 million streams in 2020; as of December 2022,Brillo has over 126 million streams onSpotify. The song became a top-20 hit in Spain and was certified platinum there for selling over 40,000 copies.^[5]
