Best ALIVE are:
Snoop (his brain is fried though)
The Game (Brought Back West Coast Rap)
Dr Dre (Amazing Rapper + HUGE Producer of all the hits)
Ice Cube (when NWA was hot he was amazing)
Eminem (though not a big fan, hes been huge)
Best Ever:
Tupac Shakur (Shakur's work is known for advocating political, economic, social, and racial equality as well as his raw descriptions of violence, drug and alcohol abuse, and conflicts with the law. Many fans, critics, and industry insiders rank him as the greatest rapper ever)
