Antojo translates to "craving" or "whim." It's a fun and relatable word that perfectly captures a strong desire for something specific.
In this song, the singer is desperate to get back with his ex. He sings, "De quitarme este antojo y volver a mirar tus ojos" (To get rid of this craving and look into your eyes again). He uses antojo to describe his intense longing to see and be with her, treating his desire like a powerful craving that needs to be satisfied.
"A Una Llamada" is about missing an ex and wanting one more chance. The singer admits he can't stop thinking about her, that pretending to just be friends isn't working, and that he's ready to pick up the phone the moment she calls.
It's a plea to undo a breakup, not to start something new. He remembers looking at her photos every night and wants to feel that closeness again, right down to looking into her eyes. The song stays hopeful rather than bitter: he believes a real conversation, a "one call away," could bring them back together.
Musically it fits classic banda romantic ballads: simple, direct lines built for singing along, with the brass arrangement giving the longing an extra lift.
