Eminem is the best at what he does,ziggy stardust and the like might be the best at what they do(its doubtful though)
>>>>>>>>>>>>Bowies weird a.ss version
but eminem isn't even undisputedly the best at what he does.. only his bats**t insane (re:you) fans would say such a thing.
wait.. did you seriously just say it is DOUBTFUL THAT MILES DAVIS AND JOHN COLTRANE ARE GREATS?? Think about it for a second, you're comparing some of the most masterful art ever conceived to a guy who raps about how much he hates his mom and celebrities.. I know Em does rap about more than that but come on how far is Marshall Mather's head shoved up your a.ss? You need help, and taste.
