“Loco” is a passionate midnight confession wrapped in the sensual rhythm of bachata. Enrique Iglesias and Romeo Santos take turns pleading with the moon to stay in the sky, hoping its light will keep their fragile love alive. The singer is on his knees, begging his partner not to leave him alone with the whirlwind of emotions that make him feel loco—crazy with desire, fear, and longing. Every kiss he imagines is meant to empty his heart completely, leaving no feelings unspoken.
The lyrics paint a vivid picture of desperate devotion: broken promises fly away like startled birds, tears threaten to drown unfinished songs, and a cracked moon hangs above like a shattered guitar. If his lover slips away at dawn, he vows he will never forgive her for the pain she leaves behind. “Loco” is both a plea and a warning, capturing the intoxicating mix of sweetness and agony that comes with loving someone so intensely that sanity itself is at stake.
