Submission + - Apple embeds account info in DRM-free music
Cardiff writes: Apple may have removed the DRM but they didn't remove tracking information from DRM-free music. With embedded account names and email information, which can be viewed only by searching the files for strings, Apple (or a record label) could easily determine the origin of a file shared on P2P. Ars speculates that Apple wants to keep an eye on casual file trading among friends.
