Justin Timberlake is about to drop the second half of his 20/20 Experience so here’s what you got to know. First of all, The 20/20 Experience 2 of 2 contains 11 tracks total and you can stream it all today over at iTunes. It’s up for preorder at iTunes today as is The 20/20 Experience – The Complete Experience which contains the 21 tracks that span the two albums. Target will once again sell an exclusive deluxe edition that contains two bonus tracks not found in the “complete” edition, oddly enough; the “complete” version also does not contain the two bonus tracks featured on the first 20/20 album.

Jump after the break to hear the second single off 2 of 2 titled “TKO;” it follows the Michael Jackson inspired “Take Back The Night.” Also below is a behind-the-scenes clip with JT and his producer/collaborator Timbaland; a 20/20 making-of documentary is teased. The 20/20 Experience  – 2 of 2 releases September 30.
