And, 'excitingly', we've already seen a bit of the documentary as the 'I'm Lovin' It' hitmaker explained to our friend and yours, Ryan Seacrest (as quoted here):
"Not to give too much away because you know I like surprising the fans, but that little piece of footage [the lyric video for 'Suit & Tie'] is from a documentary we started working on throughout the making of the album, which started last June," 'JT' explained.
He also went to on to explain the album's title.
"I was playing some of the stuff for my friends and they would come in and out of the studio, and I would say, 'Hey, what do you think of this?' My best friend said, 'This is music that you can see.' For some reason that stuck with me."
So now you know.
