CLEAN. 2013 two CD set that combines both installments in the Pop superstar's 20/20 Experience album series. The 20/20 Experience - the Complete Experience features all 21 tracks, including the first volume's 10 tracks plus 11 from Part 2 as well as a special surprise from Justin. "I originally recorded a massive amount of material and decided on the 20 tracks that I wanted on the album over a year ago. But, when I was mixing and going through all of the songs there were so many that I loved - I couldn't resist... I had to throw in something extra on the second half."
