Some critics aren't loving Justin Timberlake's "comeback" single, the throwback-y 'Suit & Tie" -- not us, read our review! However, the singer/actor is making like Charlie Sheen in the court of public opinion and winning! The song is selling like hotcakes and is projected to sell a whopping 400,000 digital downloads in its first week of availability.

In a word, JT's comeback is HUGE!

FMQB reports that the sales figure would make 'Suit & Tie' JT's biggest digital sales week ever, and it would be the largest debut for a digital single since Taylor Swift's mega smash 'We Are Never Ever Getting Back Together,' which bowed in October. So screw what the critics think. Timberlake has a hit with his fans, who have responded by buying the song, which was made available on Sunday night at midnight.

The song is also being embraced by radio, as it's Top 5 on the Billboard Pop Songs building airplay chart, tracked by BDS.

JT also posted a letter yesterday, sharing his excitement over the track and the new album he has been quietly working on since June. It will be called 'The 20/20 Experience.'

The 'Lake also used the song as a platform to launch the new look Myspace, of which he owns a large investment stake. The song was posted on the main Myspace page, which debuted after months of beta testing. Users were offered the chance to stream and/or download the song by joining the once mighty and now-lagging social networking site or by dusting off and logging into their long-dormant pages.

The redesign harks back to the Myspace of old, where music fans were able to discover bands amongst one another.

Perhaps Timberlake should drag a suit and tie out of the closet to celebrate his comeback. Call it a comeback, since that's what it is.
