So-called musicians of today merit no more than tavern singers of yesteryear: a meal, a drink, a few coins here and there for a good performance, if the audience is well-to-do. Anything more is pelf. Their stuff isn't likely to still be played a hundred years from now. Their frequent protestations about deserving more money are preposterous. What they need to do is work harder, compose and edit their existing compositions to be better.
Popularity is based upon sexual urges and aspirations, that is, what folks want to become. Rap deals with stealing, rape, and murder, so one can conclude what the listening public wants to do based upon that.
Rather than give a Pulitzer to a rap crooner, the award should be given to a teacher. Teachers work really hard and have to deal with all kinds of criticism, disrespect and long-term liabilities in today's society, one of which involves being underpaid for the work they perform.
