B'Day includes “Irreplaceable” and “Beautiful Liar.”
Beyoncé released B'Day on September 4, 2006, her 25th birthday. The title is a play on “birthday” and also refers to the record's release date. The album followed her 2003 debut Dangerously in Love and was recorded in a notably short period after Beyoncé completed filming Dreamgirls.
“Irreplaceable” became one of the album's biggest successes and topped the US Billboard Hot 100 for ten weeks. “Beautiful Liar” is a duet with Shakira and was added to the deluxe edition of B'Day; it became a major international hit.
The album's standard and deluxe editions can cause confusion when people list its tracks. “Beautiful Liar” is especially associated with the expanded edition, while “Irreplaceable” is a central single from the original album era. B'Day is therefore the specific album connecting both songs.
