I think it would be almost impossible to come up with a watermark for
audio that couldn't easily be blurred beyond recognition by fx, granular
sampling, changing bitrate etc ...
I read an article somewhere citing that previous attempts at digital
watermarking on audio have proved to be fairly easy to override - and
that's when actually duplicating entire tracks, let alone mangling samples.

surely it's virtually impossible right?
Since so many people have been asking this:
There is probably some watermarking algorithm that can be mixed with
an audio signal. It would repeat a lot throughout a recording so it
would even show up in a short sample. Potentially each watermark is
unique so every time you buy a CD, its serial number is recorded with
your name, and if unauthorized samples from that particular disc show
up, you're in trouble!
this is all paranoid rambling, but I know such algorithms exist for
audio.
