They're back! Following their surprising reunion performance at Hot 97 Summer Jam, G-Unit now unveils their first song together in five years. 'Nah What I'm Talking 'Bout' uses the instrumental from Hit-Boy & HS87's 'Grindin' My Whole Life' and essentially the same hook as well, so it's not exactly an original song. But the important thing here is 50 Cent, Lloyd Banks, Tony Yayo or Young Buck seem to be on the same page once again. Young Buck even declares, "Don't worry bout me and the Unit, we the s---, n----."

The reassembled G-Unit trades some gritty bars on this track as each member appears to be in vintage form. 50 raps, "I can get it, get it for the low / 650 n----, 4-0-0 / Blink a kilo is out the door / F--- around when I'm hustling bow / Got a hundred mil in my stash n---- / nah I'm talking 'bout / Mothaf--- that bank, I got cash n----."

While the reunion is not fully realized considering Game's absence, it appears New Orleans rapper and G-Unit Records artist Kidd Kidd may be the new member of the group as he's also featured on the track. And with G-Unit back together, there's sure to be a boost in interest surrounding 50 Cent's new album 'Animal 'Ambition' due out June 3. 50 certainly is business savvy and made this move at the perfect time.
