Laberinto translates to 'labyrinth' or 'maze'. It's a fantastic and evocative word that paints a vivid picture.
In this song, the artist sings, "me perdí en un laberinto" (I got lost in a labyrinth), referring to his lover's large eyes. This metaphor beautifully expresses the feeling of being completely captivated and mesmerized, so much so that he feels lost within their gaze.
Peso Pluma's "Por Las Noches" is a late-night message to a lover who is gone. He's alone, remembering everything about her, especially "El olor de aquel perfume sobre todo" (The smell of that perfume above all). He recalls intimate moments, like her hiding in "Las sábanas blancas" (the white sheets), and sees her as something precious and out of reach, "intocable como joya de oro" (untouchable like a golden jewel).
He's trying to move on by living a high life, mentioning "Clase Azul es el tequila" (Clase Azul is the tequila) and "Rico Prat champaña" (Rich Prat champagne). But it's clear his mind is still on her. He's so hurt that he begs her, "Si te sientes sola no me llames porfa" (If you feel lonely please don't call me), because he gets too sensitive. It's a sad song about trying to forget someone you believe is irreplaceable, when all the distractions in the world can't fill the space they left.
