Beyoncé has released a 20th anniversary deluxe edition of her 2006 album "B'Day," adding previously unheard tracks and new collaborations to mark two decades since the record's original release on 4 September 2006. The reissue's headline additions are her first-ever pairing with Colombian singer Maluma and a posthumous duet built around archival vocals from the late Selena Quintanilla, whose estate approved the release, giving long-time fans fresh material from a landmark record in her catalogue.

The new songs include "Cuerpo Tumbao (Get Me Bodied)" with Maluma, which samples Celia Cruz's "La Negra Tiene Tumbao," and "Irreemplazable (Como La Flor)," a Spanish-language reworking of "Irreplaceable" featuring Quintanilla, a fellow Texan Beyoncé has said she long admired. Other unreleased or rare tracks added include "Can I Watch You" with Pharrell, "Morning Dew (Donk)," "My First Time," "Lost Yo Mind," "Creole" and "Back Up." All songs and videos have been remastered and recoloured in 4K, and a revamped visual for "Déjà Vu" featuring Jay-Z has also been released alongside the reissue.
