Piece of Me by Britney Spears

Piece of Me is the second single from the album Blackout by American pop singer Britney Spears.

The song was written by Christian Karlsson, Pontus Winnberg, and Klas Åhlund. Swedish pop singer Robyn originally recorded a demo of this song after Klas Åhlund wrote it. Her vocals remain in the background on Britney's recorded version.

Piece of Me was officially released on January 7, 2008, in the U.S. and the UK, but had already received radio airplay before then.

Its electro-synth music, electronically-enhanced vocoder singing, and memorable hook, makes it successful in clubs, reaching number one in various Dance Club Play charts, including those in the United States and Australia. It was also one of her most successful singles in the United Kingdom, peaking at number two. Through its dance mixes, Piece of Me becomes one of those songs that DJs save for the last number.

Piece of Me debuted on November 17, 2007, on the U.S. Billboard Hot 100 at number 65, as well as at number 37 on the Canadian Hot 100.

At the 2008 MTV Video Music Awards Britney Spears won all three of her nominations for Best Female Video, Best Pop Video, and Video of the Year for Piece of Me.
