A year after her epic comeback, Jive Records decided to celebrate Britney's success of more than ten years, with a special box set entitled "The Singles Collection," featuring all 28 of her hit singles, and including a brand new song entitled "3," which she recorded with Max Martin in Sweden, whilst on her "Circus" world tour in early Summer. The raunchy electropop track discusses Britney wanting to participate in a threesome, and caused controversy for its reference to Biblical characters, Peter, Paul and Mary.
