List of number-one Billboard Top Latin Songs from the 1980s  The Hot Latin Songs chart (formerly Hot Latin 50 and Hot Latin Tracks), published in "Billboard" magazine, is a record chart based on Latin music airplay. The data were compiled by the "Billboard" chart and research department with information from 70 Spanish-language radio stations in the United States and Puerto Rico. Those radio stations were selected based on their number of listeners, and were asked to report their playlists for the week. This information was then entered to the "Billboard" computer system, and points were tabulated for each song. This data are compiled by Nielsen Broadcast Data Systems, which electronically monitors radio stations in more than 120 music markets across the United States. Before this chart's inception, the Latin music information on the magazine was presented only in the form of the biweekly album sales chart Top Latin Albums, which continues to be listed separately. During the 1980s, 33 different songs topped the chart. According to the "Billboard" electronic database, the first was "La Guirnalda" by Spanish singer Rocío Dúrcal on September 6, 1986. However, in the listings included in the first printed publication of the chart on October 4, 1986, the first number-one song was "Yo No Sé Qué Me Pasó" by Mexican singer-songwriter Juan Gabriel. By the end of that year, another of Gabriel's compositions, "De Mí Enamórate", sung by Daniela Romo, also reached number one. Also in 1986, two Spanish versions of the Italian song "Tutta la vita", performed by Franco and Emmanuel succeeded one another at the top of the chart. Two songs recorded by Spanish singer Julio Iglesias peaked at number one, "Lo Mejor de Tu Vida" and "Que No Se Rompa la Noche". These songs were released from the album "Un hombre solo", which received the Grammy Award for Best Latin Pop Performance. In 1987, a biographical film about Ritchie Valens was released and American band Los Lobos were among the musicians chosen for the movie soundtrack, since the director chose to record new music for the film rather than use Valens' own recordings. They performed the title track "La Bamba", which became a worldwide success, topping the charts in the United States (including this chart and the "Billboard" Hot 100), Australia, France, New Zealand and Switzerland. The song "Qué Te Pasa" by Mexican singer Yuri spent 16 weeks at number one in 1988, becoming the longest-running chart topper of the 1980s, followed by fellow Mexican performer Ana Gabriel, who spent 14 weeks (in two separate runs) at the top with her single "Ay Amor".
