Superarme literally means "to overcome myself" or "to surpass myself." However, in the context of this song, it's used reflexively to mean "get over me" or "move on from me."
It's an interesting word choice because it highlights the emotional distance the singer is trying to establish. The phrase "Superarme" is a direct challenge to the ex-partner, urging them to let go of the past and stop calling, making it a powerful and relatable sentiment for anyone who has gone through a breakup.
Have you ever tried to move on from someone, only for them to pop back up just when you're starting to feel okay? That's exactly what La Energia Nortena is singing about in "De Cuando Acá"! The singer is telling an ex, "puede salir con quien tú quieras" [you can go out with whoever you want] and "experimentar por mí no sientas pena" [don't feel bad for me about experimenting]. They even give permission to "borrar las fotos que conservas nuestras" [delete the photos you keep of us]. It sounds like they're trying to be super chill and mature about the breakup, right?
But then comes the twist! The singer is clearly annoyed because the ex is calling late at night, and they're definitely not alone. The blunt question, "de cuándo acá?" [since when?], shows their surprise and a bit of irritation that this person is suddenly interested again. It's like, "I thought you were gone for good, and now you're trying to come back into my life?" It's a relatable feeling of frustration when someone tries to re-enter your world after you've worked hard to get over them.
