On September 2, 2003, Sanz released his sixth studio album, "No Es lo Mismo". On this record, Sanz took a more political approach than he had on previous releases. The song "Sandy a Orilla do Mundo" discusses oil spills on the Spanish coast, while "Labana" tells the story of people fleeing from Cuba on makeshift rafts. The album won four awards at the 2004 Latin Grammy Awards, including Album of the Year and Record of the Year. Sanz was unable to attend the event and his awards were accepted by presenters and colleagues. Also in 2004, he became the first Spanish musician to give a lecture at Harvard University, speaking about Hispanic culture at the David Rockefeller Center for Latin American Studies.
