New track? Off of the 4th Quarter Under Pressure Pt. 2 mixtape. Peace to illroots.com

Eminem – Number One (prod. by Dr Dre)

update:

On Friday, an unfinished Eminem and Dr. Dre track labeled “Number One” hit the Internet. The leaked song is going to be featured on Big Mike and Neptune’s upcoming 4th Quarter Pressure Part 2. The track finds Em apparently referring to verses that Dr. Dre may rap in the finished version. According to a source close to the Shady/Aftermath camps, the record was never meant to make it off the cutting-room floor, and it’s not currently scheduled to be on either Eminem’s Relapse or Dr. Dre’s Detox. We also found out that the official title for the record is “Breaking Bottles.”
