Marcado translates to "marked" or "branded". It's a powerful word used to describe leaving a permanent impression on something or someone.
In the song, Rauw Alejandro sings, "Si mi nombre en tu piel marcado se quedó" (If my name was left marked on your skin). He uses this intense metaphor to express that his love was so unforgettable that it left a permanent mark, one that his ex's new partner can never erase. This dramatic imagery perfectly captures the song's themes of passion and possessiveness.
Puerto Rican singer Rauw Alejandro goes straight for the throat in "Dile A El", serving up a heavy dose of post-breakup jealousy, stubborn pride, and wounded ego. He sees that his ex has moved on, but he flat-out refuses to buy her story: "¿Que ya no piensas en mí? mírame a los ojos, que no te creo" ("You don't think about me anymore? Look me in the eyes, I don't believe you"). Instead of bowing out gracefully, he demands that she tell her new boyfriend the truth: "Bebé, tú dile a él que antes que todo yo fui el primero" ("Baby, tell him that before anything else, I was the first"). It is cocky, messy, and brutally honest about how tough it is to see someone replace you.
Behind all that boastful talk, though, the cracks show fast. Rauw admits he is chain-smoking over an overflowing ashtray ("El cenicero lleno, lo que hago es prender" [The ashtray is full, all I do is light up]) and confesses: "Te he llora'o en mi almohada" ("I've cried for you into my pillow"). Note the Caribbean Spanish shortcut here: llora'o drops the soft "d" sound from llorado. He flips between that sad visual and explicit memories of their physical hookups, using blunt street slang like chingar (a vulgar verb for having sex) before asking if his name is permanently burned into her memory. By the end, he tries to swallow his hurt with the lone-wolf mantra "Yo nací solo, yo muero solo" ("I was born alone, I die alone"), telling her to spread her wings while still repeating that he got there first.
