This phrase is a brilliant play on words using the verb contar. While contar literally means "to count," the phrasal verb contar con alguien means "to count on someone."
In the song's catchy hook, the singer says, "Si sabes contar, ya no cuentes conmigo," which translates to, "If you know how to count, don't count on me anymore." It's a witty and powerful way to tell an ex that the relationship is truly over, making this a very memorable phrase to learn.
This is the ultimate confident breakup anthem. It’s built around a fantastic play on words: "Si sabes contar, ya no cuentes conmigo" (If you know how to count, don't count on me anymore). The singer isn't sad about the split. Instead, they're telling their ex exactly what a huge mistake they've made. They flat-out say it's going to hurt, "Claro que te va a doler" (Of course it's going to hurt), because the ex has just lost the person who loved them most.
The song's attitude is what makes it so fun. The singer knows their own worth, declaring that while people say someone better always comes along, "en este caso hay una excepción / Es que tu ex soy yo" (in this case there's an exception / Because your ex is me). They make it clear there is no chance of getting back together, warning their ex not to count on their kisses or their touch. The final burn is a clever twist on a classic saying: "Dicen que uno siempre vuelve donde fue feliz / Y por eso yo no volví" (They say one always returns to where they were happy / And that's why I didn't come back).
