Una Na

"Una Na" was co-written by Espósito, Cuban songwriter Andy Clay, and producers Peter Akselrad, Luis Burgio and Gustavo Novello. It was produced, arranged and recorded by 3musica, and mixed by EarCandy.^[1] The song merges her pop characteristic with urban rhythms to achieve a fresh and different sound.^[2] The singer explained to Infobae that "Una Na" tells a love story, with the message "once you start feeling something for someone after that first sight, it's very difficult to go back and forget it, so you want to go deep with that story", making reference to her relationship with her boyfriend and music producer Santiago Mocorrea.^[3] The song was originally going to be titled "Una y Otra Vez" (English: "Once and Again"), but was later changed to "Una Na", repeating the last two letters of the word "Una". According to the singer, this makes the title more original.^[3][4]

In May 2017, Espósito confirmed that she had begun working on her new material and revealed the title of a new single called "Sin Enamorarnos".^[5] In July 2017, the singer published a series of videos via Instagram, announcing the release of "Una Na", which replaced the previously announced one as the lead single from her upcoming third studio album.^[6] The song was born in a jam session with Cuban producer Andy Clay in March 2017, when Espósito was promoting her previous single "Ego" in Miami, Florida.^[7][8]

Directed by Juan Ripari, the music video made its premiere on September 20, 2017 at midnight on Vevo. Hours before, scenes from the music video could be seen on advertising screens all around Buenos Aires, announcing its release.^[9] The video was shot in the Calchaquí Valleys in Salta Province, Argentina.
