Reik's three members were barely in their 20s when they released their debut, but their tender pop-rock sound came fully realized. "Amor Primero" builds to a melancholy chorus, and the soaring ballad "Noviembre Sin Ti" takes the listener back to the beginning of a failed relationship. But right when you think you have them figured out, the trio jump into “Niña” and “No Se Si Es Amor,” two rhythmic, uptempo jams that will have you singing along by the second chorus.
