My top hip hop artists/collabs/groups of the decade. none of these are decided by their technical abilities in rapping or production chops at all, but more on what and how they contribute to the hip hop genre as a whole.
Travis Miller (Lil Ugly Mane, Bedwetter, Shawn Kemp, and many other aliases)
Freddie Gibbs & Madlib
Billy Woods (+ others on the Backwoodz roster - Elucid, Armand Hammer)
