How can you tell the quality of the recording?


When you listen to music with CDs, how can you tell the quality of the recording? In other words to find out the quality of the recording what do you have to focus on? When I listen to CDs, I often notice that the recordings are not good.

Thanks.

I disagree with Rok2id. I'm sure there are systems out there that only sound really good with just one recording. That does not mean the problem is with the other recordings.
