Me arrepiento means "I regret it," from the powerful and emotional verb arrepentirse (to regret). It's a key phrase for expressing a change of heart and is central to the song's story.
In this iconic anthem, Selena sings, "Si una vez dije que te amaba, hoy me arrepiento" (If I once said I loved you, today I regret it). This declaration is the song's emotional core, transforming a memory of love into a powerful statement of empowerment and leaving the past behind.
Si Una Vez is a fiery cumbia that transforms heartbreak into pure empowerment. Over an infectious, hip-swaying rhythm, Selena sings as someone who once gave all her love to a careless partner and received only contempt in return. Instead of staying hurt, she flips the script, announcing that she regrets ever loving him and will never make that mistake again. The song captures that electrifying moment when disappointment turns into self-respect.
Each time the chorus repeats, "Si una vez dije que te amaba… hoy me arrepiento," it feels less like sorrow and more like a triumphant chant. Selena reminds us that recognizing our worth, learning from past errors, and daring to walk away can be cause for celebration. So go ahead—dance, sing along, and let this anthem be your soundtrack to moving on with confidence.
