Superé comes from the verb superar, which means 'to overcome' or 'to get over'. The -é ending is the past tense, giving the word a powerful sense of finality: the action is finished.
In "Amor Tumbado", Natanael Cano sings this as a declaration of strength. It's the emotional turning point where he confirms he has moved on from a painful breakup, making it an empowering and relatable word for anyone who has overcome a tough situation.
Natanael Cano is not crying over this breakup anymore, and he makes sure his ex knows it right out of the gate. He kicks things off with complete honesty: "Para ser directo, no me arrepiento" ("To be blunt, I don't regret it"). Their fling didn't last very long ("No fue mucho tiempo" / "It wasn't a long time"), but while it was happening, he was all in. He remembers the awful feeling of waiting by his phone—"No respondías y me moría" ("You wouldn't reply and I was dying")—while knowing she had him wrapped around her finger ("Tú me tenías y lo sabías" / "You had me and you knew it"). He admits he wasn't the kind of guy buying bouquets ("Yo no soy aquel que te dio rosas" / "I'm not the one who gave you roses"), but argues that handing over his actual heart and treating her well mattered a lot more.
Then the tables turn, and this is where the track gets hilarious and petty. Now that he has moved on ("Y lo superé" / "And I got over it"), she is suddenly the desperate one blowing up his phone: "El WhatsApp, me lo estás llenando de mensajes" ("You're filling up my WhatsApp with texts"). WhatsApp is the go-to messaging app across Mexico and Latin America, so shouting out spam texts on it grounds the drama in real life. Nata drops an English ad-lib "Lil bitch" right before laying down the law: stop calling, because "el amor también se volvió odio" ("love also turned into hate"). The song wraps up, he is over the games, and he wants his notifications silenced for good.
