Oldies and Classic Rock Radio Stations play the same music... why?

There was so much good music out of the 60s and 70s. Are they defining what the hits are? Or are they trying to bore people? It feels like they play the same 10 songs over and over again. What would we do without the internet. Are they (and this is the point of this thread) trying to censor a new movement by censoring the inspiration of the color of variety?

Please I'm interested in your opinions.
