Merced translates to 'mercy' or 'will'. The key phrase in the song is 'a tu merced', which means 'at your mercy' or 'at your command', expressing complete surrender to someone's wishes.
In this reggaeton hit, Bad Bunny uses this classic, almost chivalrous concept to describe being so captivated by a woman that he'll do anything she wants. This contrast between poetic language and a modern beat makes it a truly unique and memorable word to learn.
Bad Bunny is completely obsessed with one person in this song, and he's not subtle about it! The whole track is about him having all these other women trying to get his attention—"Tengo par de babies explotándome el cel" (I have a couple of babies blowing up my cell)—but he can only think about this one specific person. He tells her directly, "estoy a tu merced" (I'm at your mercy), giving her all the power in the situation. It's a classic reggaeton theme: a night of pure physical desire, spelled out with some very direct lines like "Tú siempre estás mojada y yo que tengo sed" (You're always wet and I'm thirsty).
He spends the song trying to convince her, promising to ignore everyone else and chase her "como Usain Bolt" (like Usain Bolt). He knows she's not looking for a slow, romantic song, saying she wants "perreo, no balada" (reggaeton, not a ballad). He even makes a funny promise that if they get together, there will be an earthquake in the bed: "en la cama va a haber un sismo." The song's vibe is all about that feeling of intense, single-minded attraction, where nothing else matters except getting that one person you can't stop thinking about.
