Costumbre translates to "habit" or "custom." It's a powerful word in this song because it explains the lingering feeling the singer has, even though he knows it's not love.
He sings, "Es la costumbre a todo lo que me diste" (It's the habit of everything you gave me), revealing that his reluctance to leave stems from routine and familiarity, not genuine affection. This offers a deeper, more nuanced understanding of a breakup than just sadness or anger.
Mexican powerhouse Carin León teams up with Colombian singer Camilo for "Ni Me Debes, Ni Te Debo" (You Don't Owe Me, I Don't Owe You), a song all about drawing a firm line under an expired relationship. The narrator admits that walking away hurts, singing "Tengo que irme porque me siento muy triste" (I have to leave because I feel very sad) and confesses he almost hesitates to leave: "Es la costumbre a todo lo que me diste" (It's habit, being used to everything you gave me). In Spanish, costumbre here carries the heavy weight of staying together just out of routine or comfort rather than real affection. Realizing that habit is not love, he decides to walk away clean so neither person carries emotional debt.
The chorus drives the finality home with a blunt sense of closure: "Ni me debes ni te debo, se acabó, nada es eterno" (You don't owe me, I don't owe you, it's over, nothing lasts forever). Instead of wallowing in bitter grudges, he sends his ex off with a slightly cheeky blessing: "Buena suerte con tu nuevo amor... para que no vuelvas con el corazón abierto" (Good luck with your new love... so you don't come back with an open heart). In English we often say a broken heart, but the phrase corazón abierto paints a vivid, literal picture of an exposed, wounded chest left vulnerable to pain. He wraps it up with "Gracias por lo malo y por lo bueno" (Thanks for the bad and the good), making sure the slate is wiped completely clean.
