straight up artistry 'in the raw' and the ability to create a 'piece of art' are two very different things', though equally significant and vital.
it's the whole 'live art' vs 'crafted art' balance. spontaneity vs manipulation. eminem will never record a piece of work like a Bboy record (IMO), just as the Bboys will never tout the natural lyrical prowess that Eminem yields (IMO). but both skills are divine nonetheless. it's the varying balance between the innate and contrived within any given artist that really chisels there own individuality. some are purely one or the other, but most straddle a personalized line somewhere in between.
music is great, isn't it?
