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 messing around in this song. He's looking back on a relationship that was short but intense. He's very direct from the start: "Para ser directo, no me arrepiento" (To be direct, I don't regret it). He admits it wasn't a long time, but his feelings were real. He says he wasn't the type to give traditional romantic gifts, but he offered something better: "Yo no soy aquel que te dio rosas / Pero te di mi corazón" (I'm not the one who gave you roses / But I gave you my heart).
But now things have changed. He says he's over it, "Y lo superé" (And I got over it), and suddenly she's the one blowing up his phone. He tells her to stop, saying "Que ya no llames" (Don't call anymore). The final line is a cold reminder of how feelings can flip: "Que el amor también se volvió odio, recordé" (That love also turned to hate, I remembered).
