Nice idea.
Better still, have 5 silent tracks each 10 minutes long and 1 track of
10 minutes ending with the chime.

Then slip in another CD with 5 silent tracks and a violent rock track
and turn the volume up full.

Or program a PIC microcontroller with a button for each 10 minute
increment and a simple DAC to create a soft chordy gong noise in
software. Bit harder than a CD though.

The person who posted the "5 silent tracks and a chime" idea should
consider that this is exactly the sort of thing that would sell to
hippies on ebay.

I wonder how much silence can be stored on a CD with standard audio
compression.
