iTunes Plus: Music is DRM free, but...

It was revealed last week, in fact, the day after Apple announced the availability of DRM-free music from its iTunes Plus store, that Apple is embedding user name and email into every DRM-free music download.  This means that what you do with the download can be tracked and traced back to you as the originator.  Why?  "The entertainment industry is obsessed with the idea of "casual piracy," or the occasional sharing of content between friends. I wouldn't be surprised if some data was being analyzed in aggregate, although Apple's current privacy policy does not appear to allow for this" (ars technica).  In any event, be sure your kids do not place DRM-free music from Apple on a peer-2-peer network, because it is all-to-easy now for the RIAA to trace it back and initiate yet another law suit.
