Album: Eminem Presents: The Re-Up

In late 2006, Shady Records was stuck in a slump. After overachieving in the early 2000s thanks to successful debuts from D12, 50 Cent, Obie Trice, and G-Unit, sophomore projects from D12, 50 Cent, and Obie Trice didn't move the needle like before while Em released Encore in the midst of his drug addiction. So there were some people doubting Shady's future. This track—produced by Em—put those doubts to bed. Not only did it feature strong verses from 50, Em, and Lloyd Banks, but it also introduced the world to Shady's newest artist Ca$his and helped Shady reassert itself. Unfortunately, the album that the song appeared on, Eminem Presents: The Re-Up, didn't really build on the momentum that this song created. But if nothing else, "You Don't Know" was a reminder that Shady was still more than relevant.
