For a limited number of albums, and usage on windows, this may be

true:

So just put it in an audio CD player with SPDIF out. (So you can copy

the watermark bit-for-bit :-) )....
To clarify some obvious confusion in previous discussion.:Watermarking

Watermarking is used to find the source of leaked copies of

copyrighted material, or, potentially, for tracking "viral" material

released into the wild.
For example, watermarking was used to name and shame --

certain journo who got a prerelease copy of albums and shared it...
