The Doctor is back on top. A mere two days after releasing his Detox single “I Need a Doctor” to digital retailers, Dr. Dre currently sits at No. 1 on the U.S. iTunes Top Songs chart.

A video for the first official single from Dre’s long-awaited album featuring Eminem and Skylar Grey was recently shot in Los Angeles with director Allen Hughes. Meanwhile, his Snoop Dogg and Akon-assisted buzz single “Kush” is No. 77 on the Billboard Hot 100.

Another comeback king, Chris Brown, sees similar success with his latest single “Look at Me Now” featuring Lil Wayne and Busta Rhymes. The Diplo and Afrojack production hold the No. 2 spot thanks to a surge in downloads. The banger comes off of Breezy’s fourth album F.A.M.E. (March 22), which has also spawned the dance floor-ready “Beautiful People” featuring Benny Benassi.

Other songs making the iTunes Top Songs chart include Bruno Mars’ “Grenade” at No. 4, Wiz Khalifa’s “Black and Yellow” at No. 5, and Pitbull’s “Hey Baby (Drop It to the Floor)” at No. 7. Alex Da Kid and Skylar Grey score another top 10 with Diddy-Dirty Money’s “Coming Home,” which lands at No. 8.
