Beyoncé Knowles furthered her reign of the pop charts in October 2006 with Irreplaceable (2006), the third single from her massively popular B’Day full-length. Produced by the hit-making Norwegian production team Stargate, the track assumes the point of view of an empowered woman who scolds her cheating lover that he’s not irreplaceable. Why anybody would ever cheat on Beyoncé is the real mystery here––the pop princess displays enough curves in the three-minute single to keep any man happy for a lifetime.
