"Gorras Numeradas" (Numbered Caps) is a full-volume corrido bélico, the warlike style the song names in its first line: "Al estilo bélico sin miedo a pelear" (War style, not afraid to fight). The crew comes down from the mountains, "Bajan de la sierra, directo van pa' la ciudad" (They come down from the sierra, straight to the city), wearing numbered caps and "no le tienen miedo a las balas" (they're not afraid of bullets).
A lot of the fun for a learner is the slang. Haciendo verdes (making greens) means making dollars. La plebada is the gang of young guys, las trocas are the trucks, caked in mud and four-by-four, and la feria is Mexican slang for money. "Puro chavalito delincuente" (Nothing but delinquent kids) is how he describes his people, with a straight face.
The second verse moves to the clubs: golden bottles, tequila, a Jeep Rubicon full of women, and the shrug "quinientos grandes pa' mí no son nada" (five hundred grand is nothing to me). It is openly about trafficking and partying, with a couple of very crude lines, so it is a bold, boastful pick rather than a gentle one.
