Justified is the debut studio album by American singer-songwriter Justin Timberlake. It was released on November 4, 2002, by Jive Records. The album was written and recorded in a six-week period, during the hiatus of the singer's band NSYNC. For the album, Timberlake began to adopt a more mature image as an R&B artist opposed to the previous pop music recorded by the group. Most of the album was produced by The Neptunes (credited as "Williams and Hugo" on the album), with additional collaborators including Brian McKnight, Scott Storch, Timbaland, The Underdogs, and Carvin & Ivan. The album features guest appearances by Janet Jackson and rap duo Clipse. Primarily an R&B album, Justified also contains influences of dance-pop, funk and soul music.
