With great power comes great responsibility, and apparently with DRM-free music comes files embedded with identifying information. Such is the situation with Apple's new DRM-free music: songs sold without DRM still have a user's full name and account e-mail embedded in them, which means that dropping that new DRM-free song on your favorite P2P network could come back to bite you.

We got curious, and wondered whether Apple might also be watermarking the underlying audio data in these tracks.
