I checked out a DJ Dmadness mixtape today called The Cee-Lo Green Mix at The Smoking Section. As you might imagine it's pretty dope. It's a pretty extensive mix of everything from Goodie Mob / Dungeon Family, to his solo work, to Gnarls Barkley with some rare tracks and b-sides, some of which I've never heard before. Most certainly worth a listen, see below for the link.
