Sin Corazón is Karol G’s sultry anthem for anyone who claims to be “over” love yet still falls headfirst into its flames. Over a hypnotic reggaetón beat, the Colombian star tells the story of two people who declare “yo no creo en el amor” but keep calling, texting, and sneaking out under the full moon because the chemistry is simply too strong. She likens their connection to a drug in her veins, a siren luring her mar to shore, and a forbidden romance worthy of Selena.
The repeated hook sin corazón (“without a heart”) is Karol G’s way of showing the emotional armor we wear after betrayal. Even so, passion burns through every line: she feels alive when he is near and empty when he is gone. The song captures that modern push-and-pull where we guard ourselves from pain yet secretly crave the rush of real feeling. In the end, “heartless” turns out to be just a slogan—desire wins, and walls melt in the heat of the night.
