Astucia translates to "cunning" or "shrewdness." It refers to the ability to achieve one's goals through cleverness and often subtle or deceptive means.
In the song, the lyric "No contaba con tu astucia" (I wasn't counting on your cunning) reveals the singer's surprise and perhaps bitterness. He implies that his ex-partner's cleverness or manipulative nature led to their breakup or her moving on so quickly, leaving him heartbroken. It's a less common word in pop lyrics, making it stand out.
Ever felt like you're stuck on pause while everyone else has hit play? That's the heart of "No Puede Ser." The song captures the shock and disbelief of seeing an ex-partner thriving and having fun just a short time after a breakup. The singer confesses, "Desde que me dejaste no salgo ni a la vereda" (Since you left me, I don't even go out to the sidewalk), highlighting a deep sense of being left behind while their former love has completely moved on.
Through a clever metaphor, the relationship is compared to a TV series left unfinished. For the singer, it's a story they desperately want to continue, but for their ex, it's an old show they've already forgotten about. The lyrics express the painful contrast between one person "revolcándome en la herida" (wallowing in the wound) and the other who seems to have forgotten everything in just a few days. It's a relatable anthem for anyone who's ever wondered, "No puede ser... que haya pasado un año y no me extrañe' todavía" (It can't be... that a year has passed and you still don't miss me).
