Valió madre is a very strong and informal Spanish idiom that literally translates to "it was worth mother," but it means "didn't give a damn" or "didn't care at all."
In the song, Yuridia sings, "No son horas de arreglar lo que ayer te valió madre" (It's not time to fix what you didn't give a damn about yesterday). This phrase powerfully conveys the protagonist's anger and frustration, highlighting how the other person's past indifference is now coming back to haunt them. It's a raw and authentic expression of resentment.
Have you ever had someone take you for granted, only to have them come crawling back when you've moved on? That's exactly what Yuridia is singing about in "No Son Horas"! She's been through it all with this person who used to leave and come back whenever they pleased, always sure she'd be there. As she says, "Tú te ibas y venías / Me tenías tan segura" [You would leave and come back / You had me so sure]. She gave everything, always being the one who gave more in the relationship.
But things have changed! The tables have turned, or as she puts it, "Dio una vuelta la moneda" [The coin flipped]. Now, when this person finally realizes what they've lost and tries to win her back, it's too late. She's blunt about it: "No me mueve nada verte" [Seeing you doesn't move me at all]. It's ironic that only now, when she's finally moved on, they want to love her the way she always asked. She tells them directly, "No son horas de buscarme / No son horas de rogarme" [It's not the time to look for me / It's not the time to beg me]. She understands their desperation because she's been there herself, but for her, it's simply too late to fix what they didn't care about before. "No son horas de arreglar / Lo que ayer te valió madre" [It's not the time to fix / What yesterday you didn't give a damn about].
