In no particular order, my favorite rap albums:
Kanye West - My Dark Twisted Fantasy
Kanye West - College Dropout
Jurrasic 5 - Quality Control
Notorious B.I.G - Ready To Die
Blackstar - Blackstar
Eminem - Marhsall Mathers LP
Nas - Stillmatic (I'm going to get a lot of hate for putting STILL but not Ill, huh?)
Jay Z - Blue Album
NWA - Straight Outta Compton
I'll admit that I haven't really listened to Wu Tang enough to put them on the list. So not an omission by me thinking it's not great music, just haven't listened enough to put it up there.
