B'Day is the second studio album by American R&B singer Beyoncé Knowles. Columbia Records, in collaboration with Music World Music and Sony Urban Music, released it worldwide on September 4, 2006 to coincide with Knowles' twenty-fifth birthday.
The album was originally planned for a 2004 release as a follow-up to her debut album Dangerously in Love. However, the project was put on hiatus due to the recording of Destiny's Child's final studio album Destiny Fulfilled and her starring role in the 2006 movie Dreamgirls. While on vacation after filming Dreamgirls, Knowles began contacting various producers; she had employed technique for faster collaboration, and completed B'Day in three weeks. Most of the lyrical content of the album was inspired by Knowles' role in the film. The album's musical style ranges from '70s to '80s funk and balladry to urban contemporary elements like hip hop and R&B. Live instrumentation was employed on most tracks as part of Knowles' vision of creating a record using live instruments.
The album was commercially successful, debuting at number one on the U.S. Billboard 200 chart. It sold 541,000 units within a week of release, beating its predecessor, Dangerously in Love. The album yielded six singles, and was successful in music markets, entering the top ten of several charts worldwide. B'Day was re-released on April 3, 2007 as an expanded double-disc deluxe edition; a DVD counterpart was also released, featuring thirteen music videos of the songs from the album. The album has earned a triple platinum certification in the United States from the Recording Industry Association of America. It spawned the worlwide hits "Déjà Vu", "Irreplaceable", "Beautiful Liar", the Canadian top 5 hit "Get Me Bodied", the U.S top 15 hit "Ring the Alarm" and the UK top 10 and 20 single respectively "Listen" and "Green Light".
