“Tu Canción” is a radiant love confession where Alfred and Amaia paint falling in love as an out-of-this-world adventure: suddenly a lunar trip feels possible, the world flips upside down, and every step becomes a brand-new dance. With lines like "Siento que bailo por primera vez" they capture the rush of experiencing everything as if it were happening for the very first time, while "Eres el arte que endulza la piel" turns the beloved into living art that sweetens every sense. The duet celebrates a partner who is both a protective voice and a creative spark, someone who can build “a new city” beside you when times get rough. Ultimately, the singers admit they can’t invent or imagine anything better than this shared song—because all they want is “tu canción,” the soundtrack of a love that makes them float, spin, and rediscover life with childlike wonder.
