The following article lists the monthly number-one songs on the MexicanSelecciones Musicales chart from January 1950 to December 1960. The source for these charts is the book Musicosas: manual del comentarista de radio y televisión by Roberto Ayala, who was the director of the Selecciones Musicales magazine. These charts were based on nationwide record sales, jukebox plays, radio and television airplay, and sheet music sales.[a][1]
As published in the Musicosas book, the charts only include the song titles and the names of the composers; the performers credited in this article are included for reference and where many performers are listed for the same song, they appear in alphabetical order, which may not reflect whose version was the most popular[b].
The longest-running number-one song of the decade was "Usted", written by Gabriel Ruiz and José Antonio Zorrilla and recorded by Los Tres Diamantes, which spent six consecutive months at the number-one position from May to October 1951.

Notes
^(Translated from Spanish) "Record agencies all over the country, jukebox operators, music publishers, recording houses and correspondents for Selecciones Musicales send local reports every week. In the headquarters, each one of those reports is assessed and by means of a scoreboard each song is rated so as to determine the position that it is to occupy on the "Hit Parade".
^While many times, like in other countries, a song would be popularized by one particular performer and it became identified with them, in Mexico it was common practice in the 1940s and 50s for a song to be recorded by various singers from different record labels around the same time; therefore, this article may not include all of the performers who recorded the songs around that period.
^Artistic name of siblings Miguel Angel and José Angel Díaz y González de Castilla.
^Also titled "No me platiques ya" or "No me platiques" in some releases
^According to the composer Vicente Garrido, Los Tres Ases were the first to make the song a success, leading Gatica and Infante to record their own versions shortly after.[2]
^The song is based on a Cuban instrumental danzón titled "Angoa", composed by Félix Reina. The Mexican musician Carlos Lico later wrote lyrics to it and recorded it with his group, Los Pao, with the new title "La boa", which became a nationwide hit when Sonora Santanera covered it.
