La Tóxica is a playful, tequila-soaked celebration of soltería in which Mexican icon Alejandro Fernández and Brazilian superstar Anitta trade verses about finally shaking off every jealous, clingy, drama-filled partner and discovering the sweet freedom of going out, doubling up on dates, and answering only to themselves and to God. With witty lines like “¿Pa' qué andar con uno si yo puedo andar con dos?” and “Cambié los chocolates por una cerveza,” the song flips the usual heartbreak narrative on its head, turning break-ups into a reason to crank up the requinto, toast another month of being single, and declare that “el que se enamora, pierde.” The upbeat Regional Mexican groove, sprinkled with modern swagger, invites listeners to laugh at past romances, dance away any lingering regrets, and wear their independence like a badge of honor—proving that sometimes the best cure for mal de amores is a loud party, good friends, and zero toxic texts.
