Eminem.
Some of his songs may be stupid, but all of his songs are FOCUSED.
All of his songs have a direct topic, drugs, mom, dad, beating, abuse, violence... etc... yet they are ALL about his life and life in general.
Tupac - rapped about struggles, life, etc..
Biggie - ^ Likewise.
Lil' Wayne - Pussy, Money, Weed..... appeals to the "younger" public.
Those that wanna play "gangsta" in mommies and daddies hard earned house/school/money.
