The Apple iTune DRM-free tracks contain user account info. I predicted they would do this with watermarking, but the info appears to be in the clear.

People are already looking for the watermark. There appears to be no watermark in the decoded audio, but the DRM-free AAC file is mysteriously larger and the DRM'ed AAC file. Watermarking embedded inside the AAC syntax? If so, clever. But not clever enough.
