Yes, Justin Timberlake has built a super successful acting career for himself, but we still miss his music!

JTMusic230.jpgJT has given us a bit of a flashback with the video above ... he's a guest vocalist on FreeSol's "Hoodes On, Hats Low," and the singer directed the video. He Tweeted it to fans on Wednesday.

Acting, directing .. what's next, Justin? More of your own music, maybe?

JT hasn't released an album since 2006's hit, FutureSex/LoveSounds.

Now, the 30-year-old actor/singer/director/whatever has Friends With Benefits in theaters; he's received critical acclaim for his role in The Social Network and he's wrapping In Time with Amanda Seyfried -- his first leading man role -- out in the fall.

Yeah, yeah, you're a big success. Bring the sexy back!
