The long-awaited album should easily score Timberlake his second No. 1 solo set.
While Justin Timberlake's long-awaited album "The 20/20 Experience" doesn't go on sale for another week, industry sources say it's going to have a blockbuster debut on Billboard's charts.
The album became available for online streaming via iTunes on Monday, giving fans their first listen.
Those in the know suggest the album could sell at least 500,000 copies in its debut week, easily securing Timberlake his second No. 1 album on the Billboard 200 chart. "20/20's" half-million forecast could grow even larger once the album reaches retailers.
