"El Azul" is a song performed by Mexican singer-songwriter Junior H and rapper Peso Pluma.

The song's title is named after Juan José Esparragoza Moreno, who is commonly referred as "El Azul".

The lyrics in the song are about the Mexican drug war, mainly about working for Mexican drug lord El Chapo, using the 701 moniker, in lyrics such as "En la sangre traigo el 701 / Melena de león, pues vengo de uno.

"[1] The lyric "Como el de aquellos botones" was censored from the song by streaming service Spotify on late April for its allusion to the drug fentanyl.

[2][3] Previous Peso Pluma songs such as "El Belicon" and "Igualito a Mi Apá" also make such references to cartels, which may be the reason Pluma received death threats by the Jalisco New Generation Cartel and had to cancel his October 14 show in Tijuana.
