In Murphy's defense, Daddy Day Care was a dope movie.Ice T went from Cop Killer to playing a detective on Law and Order.
Ice Cube went from N.W.A. to Are We There Yet?
Eddie Murphy went from Raw and movies like Coming to America/Trade Places, etc... to Daddy Day Care. Actually, Eddie Murphy may not really be as much of a sellout. I think he just stopped being funny.
Eminem is the very definition of a sell out. He's always been about making money. That's his first goal. His primary motivation is to get paid. I still think you are having trouble with this concept.
I know there are some who will say Metallica. Since they became more mainstream in the 90s and didnt stay true to what made them popular
