So much music that we never hear!

I do a lot of casual music listening both at home and in my car. My go to is local radio stations as I can get strong signals from 8 to 10 in my area. The recent consolidation of the industry is starting to show and not in a good way. There are only a few companies who own all the stations now. We music lovers know that the amount of music is vast and we can spends months with out having to play the same song or album over again. Today in radio I notice that no matter what station I listen to I keep hearing the same few songs over and over again. Even station that advertise as being different formats all play the same loops. They run commercials all at the same time and even run the same promo events. Are we witness to the death of radio and new music discovery at the hands of the corporate profit model?
