Justin Timberlake has already rocketed to No. 1 on the Billboard Hot 100 with "SexyBack," the first single from his sophomore Jive solo album, "FutureSex/LoveSounds." The set features production by Timbaland, Rick Rubin and JAWBreakers, Timberlake's behind-the-boards duo with the Black Eyed Peas' will.i.am.

will.i.am was at a loss to describe the project's musical direction when asked in January by Billboard.com. "I can't explain it, that's how dope it is," he said with a laugh. "He just surprised me again. I was surprised that I was even going to like Justin Timberlake. Then he turned me into a fan, and I've become a fan. That means you are so talented that you are changing people's vocabulary."

"FutureSex/LoveSounds" is the follow-up to 2002's "Justified," which debuted at No. 2 on The Billboard 200 and has sold more than 3.5 million copies in the United States, according to Nielsen SoundScan.
