Ah, the eternal question of a relationship: If you break up, who gets the dog? That's the subject of this album’s playful title track, but the tune is so catchy that you know love—or at least the pooch—will keep them together. The Mexican duo picked up some classic pop influences while recording in London; the bouncy "Como No" has a vintage ELO feel. And when Joy sweetly emotes on the piano/strings ballad "¡Corre!" it evokes memories of another sibling duo—the Carpenters.
