Eminem takes a swipe at Moby, NSync and Limp Bizkit in his new single Without Me.
He raps about kicking NSync's Chris Kirkpatrick and Limp Bizkit 'where the sun don't shine'.
He also says 36-year-old Moby is too old to appeal to music fans, and that 'nobody listens to techno'.
It will be released on May 20.
His new album The Eminem Show is due on June 3.
