In no particular order, and definitely not complete. Era is taken into consideration.
Big Daddy Kane
Jay-Z (hate all you want, I dare you to test an album against reasonable doubt.)
Jeru the Damaja
Missy Elliot (yeah, she makes the list)
Clipse (both of them)
LL Cool J
Run DMC (respect)
Del the Funky Homosapien
People I want to give it up to, but just don't know if I can.
Snoop Doggy Dogg
Common (I view him as more of a poet then a MC)
T.I. (I just like the dude)
Eve (although I'm pretty sure most of her stuff is ghostwritten)
