Now that Eminem's Relapse has finally hit store shelves, predictions are running rampant over how many copies Em will move (we've got our own contest here). The latest prediction says Em will sell 500,000 copies, or so, making it the year's biggest debut, but only half of what Lil Wayne sold last year, and 200,000 copies fewer than Em's last album, Encore, moved in three days. All this is speculative, but we'll have to wait until next week to find out. [Idolator]
