Songs of Mass Destruction is the fourth studio album by Annie Lennox, released on 1 October 2007 in the UK and 2 October 2007, in the U.S. The album debuted at number 7 in the UK, where it has since been certified Silver by the BPI, and number 9 in the U.S. where it sold 78,000 copies its first week. It was her first album of new material since 2003's Bare.
The first single, "Dark Road", originally appeared on Lennox's MySpace page on 15 August 2007. It was subsequently released as a single on 24 September 2007 and charted at number 58 on the UK Singles Chart.
The second single, "Sing", was released digitally on 1 December 2007 and it had a physical release as a single on 17 March 2008. "Sing" is a collaboration between Lennox and 23 other prominent female acts and artists and is a charity record aimed to raise money and awareness for the HIV/AIDS organization Treatment Action Campaign.
As Lennox reported herself on her official website, this song is about raising money and awareness for what she considers to be the HIV/AIDS genocide:
Several years ago I personally witnessed Nelson Mandela, standing in front of his former prison cell on Robben Island, addressing the world's press. His message was that the pandemic of HIV/AIDS in Africa was in fact, a genocide. Since that time I resolved to do as much as I can to bring attention to the HIV/AIDS crisis.
