Irreplaceable

In this acoustic guitar-driven burner, Beyoncé sings from the standpoint of a woman who is addressing her lover, who has been cheating on her. She's telling him that he can be easily replaced. Ne-Yo wrote the lyrics for the girl power anthem, which were inspired by his aunt and her unfaithful lover. Speaking on his VH1 Behind The Music special, the R&B singer-songwriter described how his aunt had a successful career and was very generous with her boyfriend until he cheated on her. "I remember him coming to the house," recalled Ne-Yo, "and him looking in the closet and going, 'Where's my this, where's my that?' and she said, 'Oh, in the box to the left of the closet. Everything you own is in that box and everything I bought is over here.'"

Beyoncé's Spanish language version of this song did very well, making the Top 10 on the US Hot Latin Songs chart. The title in Spanish is "Irreemplazable."

This is the second American #1 for the Norwegian production team Stargate. "So Sick" by Ne-yo was the first.
