The TikTok account @julia.martin.juli, famously known as "THE GRANDMA OF REPARTO," has once again set social media ablaze. A 44-second video featuring a Cuban grandma dancing with enviable flair to "Un tin," the latest track by Payaso x Ley, has garnered over 154,000 views.
What sets this clip apart isn't merely the grandma's spirited moves, but the song itself: "Un tin" is an unprecedented fusion of urban genre with classical operatic technique within the reparto scene. This mix is a first for the genre.
Payaso x Ley aptly describes his creation with a succinct phrase: "This is reparto with opera."
The track, released on April 20 under the Befocus Music label with the collaboration of Rowell Urban and production by Ernesto Losa, debuted its music video on TikTok on April 21. The video showcases Payaso x Ley performing in a classical lyrical style, which sparked a significant buzz online upon its release.
The grandma's video, posted last Thursday, has accumulated 18,700 likes, 1,220 comments, and 1,583 shares, making it one of the most discussed clips of the week within the Cuban TikTok community.
The account @julia.martin.juli is no stranger to viral fame; back in December 2025, it featured a seventy-year-old woman dancing reparto with such energy that it left viewers in awe.
The phenomenon of Cuban grandmas embracing the reparto rhythm has produced several memorable moments. In July 2025, a 97-year-old Cuban grandma named Luisa went viral dancing to "Tacto que llegó el reparto" by Bebeshito, accompanied by the caption: "97 years, I'm looking for her to bathe her, and she's ripping where there's music."
These videos have become a recurring viral subgenre that shatters stereotypes about age and showcases how reparto connects generations both inside and outside of Cuba.
Cuban reparto emerged around 2007 in Havana's working-class neighborhoods, incorporating elements of timba, rumba, and guaguancó. Until "Un tin," it had never borrowed from classical operatic repertoire.
With 956,500 monthly listeners on Spotify, Payaso x Ley stands out as one of the most active artists in the genre, with recent releases like "BOTA" (November 2025), "Soltera" with DJ Unic, and "Chencha" (2026).
Comments on the grandma's video poured in quickly: "I want to be like that at 70" and "That grandma has more rhythm than I do" are common sentiments among users, while "Un tin" is heralded as "the new anthem of the Cuban urban movement" on digital platforms.
