Blackout is the fifth studio album by American pop singer Britney Spears, released by Jive Records on October 27, 2007. Spears began working on this album as early as February 2006, exploring into electropop and a more R&B sound and recording with new producers such as Danja. Blackout was her first studio album in four years since 2003's In the Zone and marks the first time Spears is the executive producer of one of her albums. The album's title refers to "blacking out negativity and embracing life fully". The songs on the album are thematically focused on sex, love and Spears' relationship struggle with the media. Blackout debuted at number two on the Billboard 200, becoming her first and so far only studio album not to debut at number one due to a last-minute rules change by the Billboard music association. According to the IFPI, the album was 32nd in terms of units shipped by the end of 2007. The album's first single, "Gimme More", peaked at number one in the Canadian Hot 100 and became a top five hit in twelve countries.
