They seem always there. They're not *loud* clicks, rather a quiet but

very-often repeated sound.
This, in fact, may be simple clipping. Except that I'm not ready at this

point to think that the Chandos company would simply release a crappy

recording; copy protection seems more likely.

I have not yet tried. This is probably what I need to do next, as this

seems to be the only way to find out if this is actually copy protection

- or mere clipping. (Or perhaps I can somehow check for clipping by

looking at the waveform in something like Audacity?)
