Trastornado translates to "deranged" or "unhinged". It's a dramatic word that goes a step beyond the typical loco (crazy) you often hear in love songs.
In this bachata classic, the singer proudly calls himself "Tu loco trastornado, mami mía" (Your deranged madman, my love). He's embracing the idea that his love is so intense and all-consuming that it drives him to a state that defies all logic and sanity, making for an unforgettable declaration.
In "Inmortal," Aventura's lead singer, Romeo Santos, declares a love that's so powerful and eternal it defies all logic and science. He claims outsiders just can't understand it: "Nadie entiende cómo este amor funciona" (Nobody understands how this love works). He's so sure of his feelings that he challenges experts to study his brain, convinced they'll find his love is a medical anomaly. He even says they'll find his behavior isn't normal and that his heart was made eternal by God.
The song is full of wild, over-the-top comparisons to show just how extreme his love is. He says it's "Sólido como meteorito" (Solid like a meteorite) and that he'll love her "hasta lo infinito" (to infinity). He claims his love is so crazy that scientists are looking for a cure and that he should be in the Guinness World Records as the man who has loved a woman the most. It's a classic, dramatic bachata theme: a love so intense it's almost a form of madness, making the singer feel like his love is literally immortal.
