Retumban comes from retumbar, meaning to reverberate or make a deep, powerful booming sound. In the song, it describes the speakers booming through the street: “Bocinas retumban en esquinas” (“Speakers boom on street corners”).
It is a vivid and less common verb that helps learners express the overwhelming impact of music, sound, or even thunder.
Santa Fe Klan presents a day-to-day street routine built around smoking, music, and hanging out with his crew. The repeated line “Ya se hizo costumbre eso de andar por las nubes” [It has become a habit to be up in the clouds] uses “up in the clouds” as an image for being high. He carries someone’s “perfume,” keeps “dándole lumbre” [giving it flame, or lighting it], and says a “sábana” [a slang image for a rolled smoke] is always burning. The hook is deliberately repetitive, like the habit it describes: smoke, music, and the same cycle from Monday to Sunday.
The verses are blunt and full of street slang. He talks about dilated pupils, loud speakers shaking the corners, cold nights, parties, and “hierva sin semilla” [seedless weed]. He says, “esto ya es día con día” [this is already every day], while also admitting that the smoking affects his body and mind: “siento que las neuronas mueren pero puedo fluir” [I feel my neurons dying, but I can still flow]. Even so, the beat turns the scene into rap. “Mato bacha” means finishing the joint, and “420” is a well-known reference to cannabis culture. The song feels like a carefree but excessive snapshot of barrio life, where Santa Fe Klan says he grew up as a street kid, keeps his feet on the ground, and writes about what he lives with his homies.
