Ummmmm @lovebird yes the management works for the aritst but the management can drop the artist if they want to... hence independent artists..... alot of big time artist who once have success are independent artist becuase alot of management companies don't want to invest time and money on them if they aren't going to bring back revenue.... Roc Nation and Def Jam are both Jay-z's company so she is obligated to both.... Jay-z get a huge percentage of what Rihanna makes... then the writers, laywers, etc etc then Rihanna get what is left... that is why artists tour for so long cause they make most of their money off ticket sales.... management don't touch that money... why you think MARIAH tour for so long... and wale is doing okay in the hip hop world he has hit...
