One week before it hits shelves, part two of Justin Timberlake's The 20/20 Experience is now streaming on iTunes. The album can be streamed in its entirety on Windows, Mac OS X, and iOS. It's presented as one long audio file clocking in at an hour and 14 minutes, so you'll need to do some manual scrubbing if you want to skip ahead to one of 2 of 2's later tracks. The album — completed during the same 20-day recording session that produced part one — features guest appearances from Jay Z and Drake.

When combined with Timberlake's earlier March release, the complete, double-length 20/20 Experience spans 21 tracks. The 20/20 Experience — 2 of 2 can be pre-ordered for $10.99 on iTunes, and there's also a Complete Experience bundle on offer for $15.99. These full-length album streams have become a popular promotional tool for Apple and record labels; iTunes regularly serves up high-profile releases ahead of their street date, including Daft Punk's Random Access Memories and Hesitation Marks from Nine Inch Nails. Justin Timberlake is slated to perform as one of the iTunes Festival's final headliners on September 29th.
