BBC NEWS | Technology | Anger over DRM-free iTunes tracks

News site Ars Technica was among the first to discover that downloaded tracks free of Fairplay have embedded within them the full name and account information, including e-mail address, of who bought them.

It suggested that this information could be an anti-piracy measure as it could help work out who was putting downloads on file-sharing sites.

But it also added that the user information was found on all the tracks that people buy on iTunes whether free of DRM or not.
