As far as MD solos (or at least the ones I have)...
YOUNG BLACK BROTHA--10/10 (production's dated; otherwise, it's a must)
STUPID DOO DOO DUMB--10/10 (his best as far as flow, lyrics and production)
RAPPER GONE BAD--8/10 (worth it for "Valley Joe" alone...)
HEART OF GANGSTA...--4.5/10 (bad sound, and only eight new songs! Get the 2003 reissue instead...)
MAC DRE'S THE NAME--6.5/10 (a few cool songs, but seems cobbled together...)
IT'S NOT WHAT YOU SAY...--7.5/10 (druggy, but fun. "Chevs & Fords" is classic)
THIZZELLE WASHINGTON--7/10 (entertaining and funny, but bad engineering on a few tracks hurts)
HEART OF GANGSTA...2003 REISSUE--7.5/10 (WAY better than OG version; cleaner sound improves this)
AL BOO BOO--7.5/10 (short but tight. Worth it for the DVD)
DREGANOMICS--8/10 (cool party CD. MD sounds like he's having more fun than he has in awhile)
GENIE OF THE LAMP--8.5/10 (nice combo of Thizz and street. Some nice features make this even better)
(But my ratings on the two most recent ones could change as I let them sink in more...)
PEACE!
