"S.O.S. (Let the Music Play)" is a song performed by American R&B and pop recording artist Jordin Sparks. It is the second single from her second studio album titled Battlefield. The song was released first in Australia on September 4, 2009 and was sent to US radio on September 29, 2009. It was released in the UK on October 12, 2009. "S.O.S. (Let the Music Play)" is an uptempo electropop song which contains a sample of "Let the Music Play" by Shannon. It combines 1980s synths with modern techno-dance beats. Sparks explained why she decided to go in a dancier direction with this song: "I'll always be the ballad girl from American Idol, but I wanted to try something new, though not so far that people wouldn't believe me." The video was shot in Los Angeles, California on August 10, 2009, with Chris Robinson serving as the director. He also worked with Sparks on the "No Air" music video.
