The 20/20 Experience - 2 of 2 Songwriting Credits by Justin Timberlake

The 20/20 Experience - 2 of 2 is the fourth studio album by Justin Timberlake, released in September 2013 on RCA Records, just six months after the first volume and constituting the second half of a planned double-album project, with material from the same Timbaland-produced sessions that produced the first volume. Timberlake co-wrote all material; 'TKO,' 'Take Back the Night,' and 'Amnesia' were the principal singles from the second volume, continuing the extended-format approach with tracks that again ran well over six minutes on average. The album debuted at number one on the Billboard 200 with 300,000 first-week sales, a significant commercial decline from the first volume, reflecting both the rapid release cadence and the inherent commercial limitation of releasing album-two material so quickly. 2 of 2 has been certified double platinum in the United States and was received with more mixed critical reviews than its predecessor, with reviewers noting that the material on the second volume was less fully realized than the first. The album is primarily significant as the second panel of a single artistic statement.
