The Worst: X-Raided & Kingpen "City Of Kings". That album cover is garbage, it is just a dude blowing a cloud of smoke with a fake bootleg X-raided cap.
The Best: DJ Paul "King Of Memphis". The cover is tight and it's the only one I could think of that has droped this year.
The best of all time:
Brotha Lynch "EBK4"
X-Raided "VIM"
Eazy-E "It's On Dr Dre 187um Killa"
Eazy-E "Eazy Duz It"
Kokane "Funk Upon A Rhyme"
Above The Law "Uncle Sams Curse"
The Coup "Genocide & Juice"
Eazy-E "5150 Home 4 Tha Sick"
