Eminem flips quite a lot of his lines. You can hear him use lines in 8 mile that sounds very similar to lines on his albums... But Eminem's opponents on 8 mile weren't shit to him so, he didn't even have to try and beat them. Those 8 mile battles are actually weak as fuck, if you compare them to some of Eminem's decent freestyles the (the Canibus vs. Eminem freestyle is a good example).
