“I Wanna Go” is a song by American recording artist Britney Spears. It was released as the third single from her seventh studio album, Femme Fatale. The song was written by Shellback, Max Martin and Savan Kotecha, while being produced by Martin and Shellback. Spears first posted a snippet of the track in February 2011, prior to the album’s release. “I Wanna Go” is a dance-pop and Hi-NRG song that includes elements of techno and a heavy bassline. Accompanied with a whistled melody and stuttering vocals, the song’s lyrics feature Spears sings about losing inhibitions.
“I Wanna Go” received mixed to positive reviews from critics. Some praised the track for being effective and highlighted its hook, while others dismissed the vocals as processed. “I Wanna Go” charted due to digital sales following the release of Femme Fatale in the lower regions of the US Billboard Hot 100 and the Canadian Hot 100, and also topped the South Korean International chart for three consecutive weeks. Spears has performed “I Wanna Go” at the Femme Fatale Tour (2011).
An accompanying music video for the song, directed by Chris Marrs Piliero, premiered on June 22, 2011. The video depicts Spears lashing out against the press and the paparazzi, who are revealed to be cyborgs.
“I Wanna Go” was written by Shellback, Max Martin, and Savan Kotecha, while being produced by Martin and Shellback. It was registered on Broadcast Music Incorporated under the legal title “I I I WANNA GO O O”. On February 22, 2011, Spears posted on her Twitter account a link to a 29-second clip of the song, while calling Martin “amazing”. In an interview with Rolling Stone in March 2011, Spears stated that the song’s signature whistle gets her “every time [she] hears it”, adding that Martin’s melodies are “incredible. [...] Who would have thought of that? There is nobody I feel more comfortable collaborating with in the studio.” Kotecha spoke to Digital Spy about the song on May 3, 2011, stating that he had written it “about a year and a half ago” and it was likely a future single due to the positive reaction. A poll in which fans would choose the third single was launched on May 11, 2011. Two days later, “I Wanna Go” was officially announced as the third single from Femme Fatale by Jive Records through a press release. The cover art was revealed on June 6, 2011, and featured Spears on the music video set, wearing colored hair extensions and a top with a skeletal Mickey Mouse.
