Apple does indeed include the original purchaser in the MPEG-4 metadata. I have no idea whether or not they also do any kind of more advanced watermarking of the actual audio data itself.
My hunch; no way Apple and Amazon will not watermark. But that is just based on behavioral inference, not on knowledge or data.
