"El Ocho" is a corrido told like a news bulletin. It opens with the TV reports: "Reportaron noticieros un convoy de gente armada" (the news reported a convoy of armed people), rolling into Caborca, a town in the Sonora desert, to take control of the plaza. In this world a plaza is not a town square but a territory someone runs.
The man giving the orders is never named outright. On the radio they call him by a code: "Como el 8, esa es la clave" (Like the 8, that's the code). That number is the song's title and its whole hook. The lyrics stack up Sonora place names, Sonoyta, Altar and Caborca, and say the land answers to "los chapitos", a nickname for a faction in Mexico's cartel world. The plebes (young guys, the crew) go "camuflados van de pinto" (in camouflage, dressed in pattern), and "aguas con la voladora" means watch out for the drone, since aguas is Mexican slang for "heads up".
A few lines are nice bits of idiom to learn. "El sartén trae por el mango" (he holds the pan by the handle) means he is the one in control, even when "el agua esté revuelta" (the water is choppy). "El que es de buena madera" (the one made of good wood) is someone of solid character. And the closing brag, "aquí rifan los pelones", uses rifar, slang for being the best, and pelones (the bald ones), a nickname for the soldiers of the crew. It is a swaggering, blunt song, and very much in the narco-corrido tradition.
