When it comes to doing business they have different rates for Black and white audiences. That's the bottom line. Record companies divide the music up along ethinc lines. Again this is all done in the name of doing good business and target marketing. The reality is that there are different budgets set for each department.
Pop gets much more then urban.
Quite often entire Black departments are erased from record companies. That is never the case with pop. The ultimate goal is for a an artist to be able to 'crossover' into the pop arena. Again this is all set up by the 'supposedly open minded, colorblind music industry. One reason is to break down the stereotypes and perceptions held by advertisers that Hip Hip is thuggish black men from the hood.
