This being established, we must give Eminem some props for being the only white rapper to actually rap, (I don't know what to call the music the Beastie Boys do now, but it's far from pure rap.) and to get away with it.  More than get away with it, he kills with it, in popularity and rap respect, at least. Most rap fans rate him the best rapper working today, and while for most people that's like saying that New Orleans has the best smelling sewers of any major US city, there are a lot of rap fans out there. I'm not really one of them, but I've heard a lot of his music on the radio in stores, and the guys at work used to play his tapes constantly last year, and they weren't bad.  Certainly better than the generic half-assed gangster rap the black guys are mass producing at this point. Assuming you can overlook all the gay and female bashing he does, that is.

He's got a pretty good name too.  It doesn't really mean anything, but sounds like "M&M", which I assume is some sort of clever reference to "melts in your mouth, not in your hands", ala his rhymes are just like that.  In addition to that phonetic cleverness, it looks something like "Enemy", and sounds sort of menacing.  There's no indication of a rapper from it, but you can't have everything. He gets a bonus point for numerous law suits at and from his own mother.
