Hey DN, how bout some more hip-hop added to best albums. You got Marshall Mathers LP (good call)
but I got some more for ya:

Public Enemy- It Takes a Nation of Millions to Hold Us Back
Eric B. and Rakim- Raid in Full
NWA- Straight Out of Compton
Run DMC- King of Rock, Raising Hell
Beastie Boys- License to Ill, Paul's Boutique, Ill Communication
Dr. Dre- The Chronic
Notorious B.I.G.- Ready to Die

*I didn't put down 2pac although he's one of my fav's. I figure Pat talks enough about him and people may get tired of it. Out.
