While on tour, Martin returned to the studio to record his fourth album "Vuelve" (1998). He called the experience of touring and recording at the same time "brutal and incredibly intense". As he was finishing the record, the singer was contacted by FIFA to write a song for the 1998 World Cup; Martin subsequently wrote "La copa de la vida" with K. C. Porter and Draco Rosa. He performed the song at the World Cup final in the Stade de France on July 12, 1998. The performance, which was broadcast to over a billion viewers in 187 countries, was described as a "global moment for Latin pop". "La copa de la vida" reached No. 1 on the charts around the world and went gold and platinum in various countries. It was awarded Pop Song of the Year at the 1999 Lo Nuestro Awards. The title track and the ballad "Perdido Sin Tí" both hit number one on the Hot Latin Songs. Further singles included: "La Bomba", "Por Arriba, Por Abajo" and "Corazonado". "Vuelve" spent twenty-six weeks at number one on the Billboard Top Latin Albums. It became Martin's first top forty album on the "Billboard" 200 in the United States, where it was certified platinum by the RIAA. The album also went to number one in Spain and Norway, and sold over eight million copies worldwide.
