T.I. throws a gangsta party with Dr. Dre on “Popped Off,” their completed collaboration off Tip’s new mixtape F*ck Da City Up.

“It’s been a while since ya’ll heard these beats, you’re malnourished/ But he’s back now to flood these streets and shall flourish,”

raps the Doc over the Dre-produced beat, which samples Kool & the Gang’s “Summer Madness.”

“He got hot beats and I got dope rhymes, so we can always get together and make music,” Tip told MTV News of working with the West Coast icon. “But for people to feel what we’re sayin’ and for it to sound like a party comin’ through your speakers, you gonna have to create some chemistry. So that’s what we spent more time doin’ than anything else; developing that chemistry.”

Light the chronic and let the good times roll.
