I can't say I have a favorite, but some of them are:
Hitman - Solo Creep, that shit is raw as fuck with his name as the bullet
B-Legit - Tryin to Get A But, how hard is that shit, taken outside a liquor store wit him bout to pull a jack, that shit is raw
Too $hort - Get In Where U Fit In, classic cover, with the Oakland skyline in the back, $hort all pimped out
