Justin Timberlake's comeback single, "Suit and Tie," is on track to sell an estimated 330,000 to 350,000 downloads in its first week, making it his best sales week ever for a song, Billboard reports.

Though the song is currently only available on iTunes, early forecasts put sales for "Suit and Tie" – the first single from Timberlake's long-awaited new album The 20/20 Experience – around 400,000. While it may not hit that mark, the new estimate greatly surpasses first week sales for 2006's "SexyBack," which had 250,000 downloads.

"Suit and Tie" will debut on Billboard's Hot 100 this week, most likely in the charts' lower half, on the strength of radio play alone. Next week, however, once sales and streaming are factored in, the track could compete for the top spot.

Only seven songs in the past year have debuted with 300,000 or more sales, with the biggest seller being Taylor Swift's "We Are Never Ever Getting Back Together" at 623,000.
