If the idea is to have an anthology/sampler, then there is no room for the totally arbitrary and generally worthless notion that the music from 1963 - 1976 was "better."
There has been an explosion of music recording and a proliferation of subgenres in these years that dwarfs what happened between 1963 and 1976. *You* find the prospect of listening to 250 albums from between these years to be a chore? Well tough sh!t, dummy. You've already demonstrated a particularly large knowledge and understanding deficiency when it comes to music, so get cracking on improving yourself and at least working yourself up to "average." You still lag far, far behind the mean level of this board in this regard. You may get there in another 10-15 years or so, but the only way to do so is to put your head down, embrace humility, and continue to listen.
