Eminem To Judge Rap Battle: Names No 1 Stan

Eminem is set to judge Vibe Magazine's upcoming "Vibe Verses Presents No. 1 Stan" competition where the winner has to do a live battle rap in order to take the big prize home. A group of aspiring MCs hand-picked by Eminem himself will find themselves fighting it out to see who has the skills to earn the title.

The contest is in celebration of Vibe's "Real Rap" issue hitting stands on May 19th (the same day as Eminem's upcoming "Relapse" album). Participants will upload a 60-second video clip of themselves freestyling over the instrumental track of Eminem's "Stan" single.

"Battling is the way I came up, so it's gonna be interesting to watch a rap battle unfold online," Eminem said about the contest. "Vibe is taking it out of the clubs and street corners and putting it on the Net. MCs better bring it, because I'm watching."

All entries are due by April 21st by visiting numberonestan.com. The top 10 finalists, determined by a Vibe.com user voting system, will be sent another instrumental track to rhyme over for an additional 60 seconds with the final results passed on to Eminem to judge. Em will then pick the top two rappers by May 8th and they will be flown to a special Vibe event where the winner will be determined by an audience vote. The winner will get an engraved microphone dubbing them Eminem's "No. 1 Stan" and they will be featured in the magazine.
