So billboard is reporting this is the first taste of music from Dr. Dre's long awaited album Detox:
"It may just be a few seconds of music, but Dr. Dre fans will remember the new Dr. Pepper ad as the spot where they heard the first officially released beats from the much-delayed Detox.
The L.A.-based hip-hop producer appears in the last installment of an ad campaign entitled Trust Me, I’m A Doctor, and teases music from the long-awaited album, currently slated for a late 2009 release on Aftermath/Interscope. The commercial will begin airing on Monday, June 1."
Turns out it's one of the T.I. reference songs he did for Dre a while back, the track most definitely go hard but lets be real... chances are it won't end up on Detox.
