Estupidez translates to "stupidity" or "a foolish act." It's a strong, direct word that isn't commonly featured in every pop song, making it stand out.
In the context of "Si Por Mí Fuera," the singer uses it to describe the foolishness of continuing a toxic relationship: "Seguir en esto parece una estupidez" (Continuing this seems like stupidity). This word perfectly captures the frustration and self-awareness of realizing one is stuck in a bad cycle, adding a raw, relatable emotion to the lyrics.
In Kenia OS's "Si por Mí Fuera," we hear a story about that classic dilemma: knowing someone isn't good for you, but still feeling drawn to them. She's got "Cuatro mil motivos tengo para no volver" [I have four thousand reasons not to come back], and she tells herself this right before she falls for them again. We've all been there, right?
She knows this person won't change, and that they'll just "joder" [mess it up] again. Even though her heart might want to give them another chance, her head knows better. She sings, "Mejor de una me voy rápido" [It's better if I leave quickly] because it's more practical. It's a really relatable song about breaking free from a cycle, even when it's hard to let go of those "ricos tus besos" [your rich kisses].
