Early indications are that Justin Timberlake ’s music comeback is a success.

Billboard predicts that his just-released collaboration with Jay-Z , “Suit & Tie,” could sell at least 400 thousand downloads for the week ending Sunday.

To put that number into perspective, Justin’s fastest-selling single to date, “SexyBack,” racked up 250 thousand downloads during its first week of release in 2006.

Justin is preparing for the debut of his new album, The 20/20 Experience , later this year.  It will be his first disc since FutureSex/LoveSounds dropped in 2006.
