Are we really that surprised?

Hip Hop and even rap has changed dramatically over time. There is no going around that. Sure now rap is all about money, drugs, and bitches, but honestly, are we surprised? Many people seem shocked that it has come to this, but why? We saw bands like the Beach Boys steal music to make hits, we saw bands from the 80s fit a cliche mold of dancing and singing (aka the pop start), we saw MTV change from a video channel to a reality channel, and now Hip Hop turning into music about partying and nothing real. Rather than complain about how our world changes in a way that makes all music and pretty much all aspects of our life cookie cutter, why don't we ask why. I am most definitely glad we have people who decide to break the mold like Drease and Immortal Technique (who by the way is not suitable for children to listen to considering he swears a lot and talks about gang rape, I saw that in a previous post). The ones who go out of the box makes society realise that there is more than what is played constantly on the radio, and that there is more than what mainstream is providing. An ideal world would have many more of these artists, but unfortunately that is unrealistic. Why? Because it doesn't make money. WHY DOESN'T IT MAKE MONEY? Why is it that our world is willing to buy music that contains really dumb lyrics as suppose to an intellectual rapping or singing about real issues. Its a mystery.
