Music industry sources predicted that Justin Timberlake's The 20/20 Experience could sell between 850,000 and 900,000 when final numbers come in at the end of the tracking week on Sunday, March 24, according to Billboard.

Estimates on May 11, months before the RCA Records album came out on March 19, noted that the album was headed for at least 500,000 sales. Since the album's release the sales projection numbers jumped to 750,000 on March 20th, 800,000 on the 21st and 850,000 to 900,000 on March 22. Steady sales over the weekend could make the number rise even higher.

With its soaring sales, Experience could become the year's top-selling album and top Mumford & Sons' Babel, which has sold 631,000 so far in 2013, according to Nielsen SoundScan. There have only been 31 instances where an album sold more than 850,000 copies in a single week since SoundScan started tracking data in 1991, according to the magazine. The all-time best-selling week was with Timberlake's former group 'N Sync and its No Strings Attached album. It debuted with 2.42 million at No. 1 on the April 8, 2000, Billboard 200 chart.

The top two biggest debuts of the decade so far belong to Taylor Swift, followed by Lady Gaga and Lil Wayne.

At his album release party on March 18, Timberlake announced a second half of his new album to be released later in the year. He told the crowd at Los Angeles' El Rey Theatre, "I need to clear up a rumor." He then addressed claims that his new album is only "the first half of the album."

"Those rumors are true," Timberlake said, before teasing that he will not reveal a release date just yet.

A day later he premiered an eight-minute music video for the second single off of his new album: Mirrors. The Tennessee native dedicated the video to his grandparents Sadie and her late husband Williams Bomar, who passed away last year.
