they dont get all their money from just rappin, like P. diddy was a producer until Biggie tried 2 get him 2 rap again which he did. if u did a point system on rap cd's that sell, if one cd is 100 pts , the rapper gets like 3 pts out of that 100, and the rest goes to producers and managers and publishing and shit like that, also the big rappers, eminem p diddy 50 cent, they all got their own clothing lines, which they get huge doe from
