CD plays "scratchy"... why?

[decoherent]

This is in response to a response from Ricky. He asked if the orginal
CD was one that was burned. No, it was not. It was an original that
was used often in seminars as background music. I am going to try
to get another original CD to see if it will play better. Thanks for
the suggestions.

I wouldnt use the lens cleaning kit if other CDs work. It would be
best to encode that audio CD into mp3 and play it from HDD, or from
data CD, cause data CDs have error correction, etc.
