El Tóxico turns heartbreak into a fiery ranchera drama.
In this anthem of wounded pride, Grupo Firme and Carin León flip the usual breakup script. Instead of begging for a second chance, the singer vows to become the ex from your worst nightmares. He once gave everything—his love, his life, even “a thousand reasons” to stay—but after being left without explanation, he promises payback. From poisoning the dog to haunting every memory, he plans to be an inescapable reminder of regret. Beneath the playful exaggeration and colorful insults lies a familiar feeling: when love turns sour, anger can feel like the only way to keep the hurt from winning. The song mixes humor, swagger, and raw emotion, showing that in Regional Mexican music, even revenge can come with an infectious beat.
Grupo Firme is a dynamic regional Mexican band originating from Tijuana, Baja California, Mexico, known for their vibrant fusion of Pacific/Sinaloan norteño, Sinaloan banda, and norteño-banda styles. Founded in 2014 by Eduin Cazares and Jairo Corrales, the group quickly rose to prominence with hits like "Pídeme" and "Juro Por Dios," captivating fans across Mexico and the United States.
Winning multiple awards including Latin Grammys and Premio Lo Nuestro honors, Grupo Firme has established itself as a powerhouse in contemporary Mexican music. Their energetic live performances, such as the stadium tour "Enfiestados y Amanecidos," showcase their connection with audiences. Collaborations with stars like Maluma, Thalía, and Demi Lovato highlight their versatile appeal and continue to expand their reach in the Latin music scene.
