“Beso Amargo” (Spanish for “Bitter Kiss”) plunges us into a late-night phone call between two lovers who just can’t quit each other. Over moody trap beats, German artist C.R.O sings from the perspective of a man who promises to rescue his partner whenever she feels lost in the city, even though he knows their relationship is a roller-coaster of break-ups and reconciliations. The repeated plea “Tú llámame” (“Call me”) shows his readiness to be her safe place, while acknowledging that their passion often turns sour, giving them the "beso amargo" that both heals and hurts.
At its core, the track captures the push-and-pull of a toxic yet addictive love: jealousy, fiery arguments, irresistible bedroom chemistry, and the constant hope that they can still “shine” together. C.R.O admits that no one else will ever understand what this mysterious woman hides inside, and that he is “about to go crazy” trying to decode her. The song’s bittersweet message is clear: sometimes the lips you crave the most leave the sharpest taste, yet you still reach for the phone and hit redial. Who said love was rational?
