Kanyes got to be well up there in the producing game making some crazy beats not just for himself, but alot of other artists. Common, Jay-Z, The Game & Shyne are just a few of raps biggest names that have rapped over 1 of his beats. Dre is still 1 of the great producers, he's been around for like 20 yrs and can still make a beat. I like Lil Jon's style, with the huge bass-lines and Scott Storch. But The Alchemist doesn't make many good beats.
