Could Justin Timberlake be making a slow but steady (and sexy) return back to music?

In April, the singer appeared in and directed a video for the band FreeSol. Now, he's in their latest video -- and he steps up his game by RAPPING!

We love this side of JT. Watch it all above! JT hasn't released an album since 2006's hit, FutureSex/LoveSounds.
