One point bears making.

I have never come across an undamaged 'pressed' CD that would not play in a normal audio CD player, whether as part of a hifi setup or as a computer component. I do, however, have a number of CDRs (from a reputable small label) that will only play successfully in one player out of four (and that in a computer).

It's not so much an issue of inherent sound quality as of compatibility and construction, I suspect.
