- Artist: Eminem
- Track: You Don't Know
- Feat. Lloyd Banks, 50 Cent, Ca$his
- Producer: Eminem
- Album: Eminem Presents: The Re-Up
After originally hooking up with DJ Whoo Kid and The Alchemist to do a Shady Records mixtape for the streets, Eminem and his label executives had a change of heart. The material being churned out was simply too good to be released on anything except a major release and thus comes the Re-Up Mixtape, out in stores on December 5th. The first cut to be released from the album features Em's Shady/G-Unit family which includes 50 Cent, Lloyd Banks and newcomer out of Los Angeles, Ca$his. The beat comes courtesy of Slim Shady himself and showcases his ability to highlight fellow artists on a collaboration, without having to weaken his own performance in the process.
