a escondidas is a Spanish phrase that means "in secret" or "secretly". It's used to describe actions done covertly, away from prying eyes.
In the song, Junior H sings about a clandestine romance, referencing secret meetups ("esto es a escondidas") and forbidden photos ("Las fotos están prohibidas"). This evocative phrase paints a picture of a passionate, hidden affair, making you want to uncover the story behind the lyrics.
DROGA LETAL sets up a late-night romance wrapped in luxury cars, mezcal, and dangerous habits. Mexican artist Junior H teams up with Gael Valenzuela and Peso Pluma to trade verses about a woman whose company feels intoxicating. The setting is direct and lavish: you have candlelight in a bedroom, the sea, bottles of mezcal, and an Audi R8. Junior bluntly admits it took him just five minutes of talking in that sports car to fall for her, promising "Yo no soy ningún Pinocho, yo soy tu rockstar" ("I'm no Pinocchio, I'm your rockstar") to prove he is telling the truth instead of spinning fairy tales.
What makes the track stick is the secrecy. The singers compare their fling to Gina Montana and Manny from the movie Scarface, keeping things strictly on the down-low: "Las fotos están prohibidas" ("Photos are forbidden"). You get street slang mixed into the romance too, like "una bolsita para alivianar" ("a little bag to ease up") and "la mata sigue dando" (an idiom literally meaning "the bush keeps producing," used here to mean the good times and cash keep flowing). Between flashing heavy gold chains, firing rifles ("jalarle al cuerno"), and driving fast, the hook always returns to the physical obsession: she really is his droga letal ("lethal drug").
