Regional Mexican Airplay (also referred to as Regional Mexican Songs) is a record chart published by Billboard magazine. It was established by the magazine on October 8, 1994, with "La Niña Fresa" by Banda Zeta being the first number-one song on the chart.[1] The chart mainly focuses on the styles of music from the different rural regions of Mexico such as mariachi, norteño, and banda, as well as the Mexican-American community in the United States such as Tejano. These genres are collectively referred to as "regional Mexican" under the Latin music umbrella.
This chart features only singles or tracks and like most Billboard charts, is based on airplay; the radio charts are compiled using information tracked by from Nielsen Broadcast Data Systems (BDS), which electronically monitors radio stations in more than 140 markets across the United States. The audience charts cross-reference BDS data with listener information compiled by the Arbitron ratings system to determine the approximate number of audience impressions made for plays in each daypart.[2] The current number-one song on the chart is "Aquí Mando Yo" by Los Tigres del Norte.[3]
In 2018, Billboard magazine compiled a ranking of the 20 best-performing songs on the chart since its inception in 1994. The chart is based on the most number of weeks the song spent on top of the chart. For songs with the same number of weeks at number one, they are ranked by the most weeks in the top ten, followed by most total weeks on the chart. The list was updated in 2021.[20]
