Subscriber's Email Address Remains In DRM-Free Tracks From iTunes

Writing on CNet.UK, Nate Lanxon says that all though DRM has been removed from iTunes tracks, consumers should be aware that these files do still have the email address of the iTunes subscriber.

Although iTunes Plus files feature no copy protection, files downloaded still contain the email address you have registered with iTunes. So although files can physically be shared with, and played by, friends and family, any of your purchases that end up on file-sharing networks, for example, can be traced back to you.

If you're interested in an easy way to check your own files, find an iTunes Plus file on your computer. Then choose to open it with a text editor (Windows Notepad works fine). It'll take a while to open and will appear to be full of nonsense text, but if you choose the 'Find' option and type in the email address you have registered with the iTunes Store, you'll find that your DRM-free music is not personal information-free.
