Britney Spears discography

American singer Britney Spears has released nine studio albums, seven compilation albums, forty-two singles, two promotional singles, and has made three guest appearances. In 1997, Spears signed a recording contract with American record label Jive Records in order to launch her career.

Spears made her chart debut in November 1998 with "...Baby One More Time", which was followed by the release of her debut studio album, ...Baby One More Time (1999). The record opened the Canadian Albums Chart and the US Billboard 200 at number one, being later certified fourteen times Platinum by the Recording Industry Association of America (RIAA). The singer's second studio album, Oops!... I Did It Again, was made available for consumption on May 16, 2000, and became the fastest-selling record ever by a female act in America, bringing first-week sales of 1,319,193 units. It spawned four singles—"Oops!... I Did It Again", "Lucky", "Stronger", and "Don't Let Me Be the Last to Know". In November 2001, the singer's eponymous album spawned worldwide hit "I'm a Slave 4 U", which had been pointed out by music critics for being a musical departure from her previous material. After a two-year hiatus from her career, Spears's released her fourth studio album, In the Zone, in November 2003, which featured "Me Against the Music"—a collaboration with Madonna that reached the top position of the European Hot 100 Singles—and "Toxic", which earned Spears her first Grammy in the category of Best Dance Recording, and gained her credibility among critics. The singer's first compilation album, Greatest Hits: My Prerogative, was released the following year and sold nearly six million copies worldwide.

Following experiencing personal struggles through 2007, Spears' fifth studio album, Blackout, was released in October of the same year. Unlike all of the singer's previous records, Blackout failed to be heavily promoted through magazine interviews, talk-show appearances or televised performances—besides a performance at the 2007 MTV Video Music Awards—and was not accompanied by a supporting tour either. Even so, it was able to sell over three million units worldwide, spawning commercially acclaimed recordings "Gimme More" and "Piece of Me". With the release of her sixth studio album Circus, Spears became the only act in the Nielsen SoundScan era—from 1991 to present,—to have four records debuting with 500,000 or more copies sold in the United States. Supported by the releases of "Womanizer" and "Circus", it managed to sale four million copies globally. The singer's third compilation album, The Singles Collection, featured her third number one single in America, "3". In 2011, she released the song "Hold It Against Me", which made Spears the second artist in the Billboard Hot 100's 52-year history to debut at number one with two or more songs, just behind American recording artist Mariah Carey. The track was included on her seventh studio album, Femme Fatale, which debuted at number one in that country. Spears's eighth studio album, Britney Jean, was released in 2013. Receiving mixed reviews from music critics, it experienced minor commercial success, and thus became the lowest-selling record of her career. Spears began working on her ninth studio album in 2014; she also renewed her record deal with RCA Records. Glory was released in 2016 and received positive reviews from music critics.The album debuted at number three on US Billboard 200 with 111,000 album equivalent units sold.

Spears has sold over 100 million records worldwide and more than 28.6 million digital singles in the United States, making her one of the best-selling music artists of all time. Billboard ranked her the eighth overall Artist of the Decade, and also recognized her as the best-selling female album artist of the 21st century's first decade, as well as the fifth overall. Additionally, the Recording Industry Association of America recognized Spears as the eighth best-selling female artist in the United States, with 34 million certified albums. The singer serves as one of the few artists in history to have a number one single and studio album in each of the three decades of their career—1990s, 2000s, and 2010s.
