One song on its first disc was supposed to be recorded by Leona Lewis, who was too busy to lay down the track. That song, "Halo," would later be released concurrently with another song, "Diva." Featuring the name of the performer's alter ego in its title, this album has also spawned the smash hits "If I Were a Boy" and the danceable "Single Ladies (Put a Ring on It)." For ten points, name this album, the most recent from Beyoncé.
