Beyoncé's 2006 album B'Day was titled after a shortened form of “birthday.”
B'Day was Beyoncé's second solo studio album and was released on September 4, 2006, her 25th birthday. The title is a stylized abbreviation of “birthday,” while the letter B also points to Beyoncé. The album followed her debut, Dangerously in Love, and arrived while she was expanding her acting career.
Its songs include “Déjà Vu,” “Irreplaceable,” “Beautiful Liar,” and “Get Me Bodied.” The album earned strong commercial results and won the Grammy for Best Contemporary R&B Album at the 49th Annual Grammy Awards in 2007.
A common mix-up is calling 4 her second album because 4 is a prominent title; in fact, 4 was her fourth solo studio album. B'Day also differs from Beyoncé's later self-titled visual album, which was released without warning in 2013.
