"Piece of Me" is a song by American recording artist Britney Spears from her fifth studio album, Blackout. It was released on November 27, 2007 by Jive Records as the second single from the album. The song was co-written and produced by Bloodshy & Avant as a response to the media scrutiny and sensationalism of Spears's private life, which they had seen by working with her over the years. "Piece of Me" was the last song to be recorded for Blackout. The self-manifesto song's lyrics are written like a biography retelling her mishaps. Musically, "Piece of Me" is an electro song that runs through a down-tempo dance beat. Spears's voice is heavily synthesized, and constantly shifts in pitch. Backing vocals are provided by Bloodshy & Avant and Robyn.
