"SOS" is a song by Barbadian recording artist Rihanna from her second studio album, A Girl like Me. The song was produced by J. R. Rotem and written by Rotem and Evan "Kidd" Bogart. It was released as the lead single from the album. The song is an uptempo dance song that samples the key section, bass line, and drum beat from Soft Cell's 1981 single "Tainted Love". The song was well-received by some critics for sampling "Tainted Love" by Soft Cell while others compared it to "Pon de Replay". It became Rihanna's first number-one single on the Billboard Hot 100 and also topped the charts in Australia and Canada as well as reaching the top five in other music markets such as Germany, Republic of Ireland, Switzerland and the United Kingdom. In the UK, SOS was nominated for The Record of the Year, but lost to Patience (Take That song) by Take That.
