‘You Don’t Know’ has been taken from the forthcoming Eminem Presents album entitled ‘The RE-UP’. This was originally conceived as a mixtape to introduce new Shady Records (Eminem’s label) artists to the masses, “but what happened is that the material was so good and the tracks were getting produced like a regular album” said Eminem. So they decided to treat it that way and give it a commercial release.

The album introduces new Shady artists: Stat Quo, Ca$his and Bobby Creekwater. It also features brand new music from Eminem, 50 Cent, Lloyd Banks, D12, Obie Trice, Akon and production from The Alchemist (best known for his work with Cypress Hill, Nas and Snoop Dogg). The RE-UP was executively produced by Eminem who also produced the majority of the tracks.
