Sanz spent two years in Milan, Italy to work on a follow-up for "3". For the album, he wished to create a "true fusion" of many different sounds, and began studying the saxophone and piano in addition to guitar. In 1997, Sanz released his fifth studio album, "Más", a record containing ballads strongly influenced by flamenco, pop, and tropical rhythms. Driven by the singles "Corazón Partío", "Y, ¿Si Fuera Ella?", "Amiga Mía", "Aquello Que Me Diste", and "Siempre Es de Noche", "Más" sold more than two million copies in Spain and was certified 22× Platinum in the country, making it the best-selling album in Spanish history. The album remained on the "Billboard" Latin Albums chart for 74 weeks, and one year after the record's release, Sanz was granted an Ondas Award for Best Song for "Corazón Partío". According to David Cazares of the "South Florida Sun-Sentinel", the album "made Sanz an international star on the strength of the pop-salsa hit 'Corazón Partío', a song on the lips of fans from Spain to Cuba and the United States." Following the success of the album, Sanz began touring in United States for the first time.
