B'Day is the title of Beyoncé’s 2006 studio album featuring “Déjà Vu.”
B'Day is Beyoncé’s second solo studio album, following Dangerously in Love. It was released on September 4, 2006, Beyoncé’s 25th birthday. The album’s title is a play on “birthday” and also reflects the timing of its release.
“Déjà Vu,” featuring JAY-Z, served as the lead single. Other songs from the album include “Irreplaceable,” “Ring the Alarm,” and “Beautiful Liar,” the latter appearing on a deluxe edition as a collaboration with Shakira.
B'Day was recorded in a relatively short period after Beyoncé completed filming Dreamgirls. The album blends contemporary R&B, pop, funk, and soul influences. Its title is often confused with the name of a birthday celebration, but the canonical album styling is B'Day, with an apostrophe.
