While The 20/20 Experience was all about dance commands, sexytime, and Jetsons-appropriate vehicles, 2 of 2 might be the dark half of things, with tracks like “Murder,†“Amnesia,†“Drink You Away,†and “T.K.O.†There’s also a song called “True Blood†and another called “Cabaret.†In tandem with the Sept. 30 release date, Timberlake will sell The Full Experience as a four-disc vinyl set. (If you’re not into spending $58 on JT, there’ll be a CD set too, and a standalone version of 2 of 2.)
