Well it's being reported by newsnerd.com that Jay is saying just that.  He claims Eminem had some great verses but to be the biggest selling of all time is an overstatement.  You can check out the full article here http://www.thenewsnerd.com/music/jay-z-says-eminem-overrated-rapper-time/

Question is why is Jay going at Eminem that way?  Is he looking to take him off the Rapp Throne?  I know you've seen the pics of Em overseas performing in front of 75,000+ fans.  Eminem is a global rapp phenom.  Could Jay be jealous?  Or is he keeping it real?  What do you think?  Take the poll question becuase you know I'm going to speak about this on Saturday!

Poll: Is Jay Z right? Eminem most overrated?
