Aniquilado literally means "annihilated" or "destroyed". It's a very strong and dramatic word that you don't typically find in a romantic song.
Juanes uses this powerful verb to express the utter devastation he feels when his loved one isn't there: "Me siento aniquilado si no estás" (I feel annihilated if you're not here). This intense exaggeration paints a vivid picture of emotional collapse, making it an impactful word that captures the song's passion.
Colombian rocker Juanes trades heavy riffs for pure romantic devotion in this acoustic-driven anthem. He lays his cards face-up right from the start: waking up next to his partner leaves him completely rejuvenated ("Me siento renovado" [I feel renewed]), but having them disappear turns him entirely inside out. He goes from feeling refreshed to outright destroyed ("aniquilado" [annihilated]) the second they vanish. Without his love around, he describes himself roaming like a wandering beggar ("un vagabundo" [a vagabond]) and feeling totally disorganized ("desordenado" [messy / out of sorts]). It is dramatic, sweet, and wonderfully over-the-top.
The real joy of the track comes from its soaring chorus, where Juanes spells out every single bodily reaction triggered by this person. When he sings "Es por ti" (It's because of you), he credits them with reigniting his pulse ("late mi corazón" [my heart beats]), bringing light back to his eyes, and soothing his pain ("calma mi dolor" [it calms my pain]). He even hits you with vivid, sun-soaked poetry, comparing their skin to the shade of a fiery sunset ("un rojo atardecer" [a red sunset]) and claiming their eyes literally steer him toward the sun. It is a warm, unashamed confession of how one person can completely reset your world.
