Best rapper of each year since 1979

I ran across this long article describing who the authors claim to be the most important, influential rapper of each year since 1979.  My familiarity with the artists and their music starts waning around 2004, when I graduated from college and left Chicago soon after.  But reading this makes me think it would be a cool personal project to listen to the highlighted album from each year on this list (as if I had the free time to actually do such a thing.)
