Relleno literally means "filling" or "stuffing," like the filling in a sandwich or a pillow. However, in this song, Jay Wheeler uses it metaphorically in a very impactful way.
He sings, "Todas estas cabronas son relleno," meaning "All these other women are just filler." It powerfully conveys that despite being with others, they are insignificant and can't compare to his lost love, highlighting his deep longing and the emptiness he feels.
Frío (Spanish for cold) is Jay Wheeler’s raw confession of heartbreak. The Puerto Rican singer compares life after a breakup to an endless winter: the house feels too big, the air-conditioner chills his bones, and even familiar songs remind him of the warmth he has lost. Through vivid lyrics he describes how love once felt intimate and real, yet a single mistake left him trapped in an “infierno” of loneliness.
Unable to forget his ex, Wheeler scrolls through her social-media photos and feels a stab of jealousy, admitting that no new fling can replace her. The chorus repeats his regret—“la cagué contigo” (I messed it up with you)—turning the track into both a love letter and a self-inflicted scolding. Frío blends sensual memories with emotional frostbite, inviting listeners to dance while reflecting on the heat of a love that slipped away.
