iTunes Plus is a big step in the right direction. There is technically no DRM on the "plus" files you buy through the iTunes Store. However I'm told that your email address / Apple ID is still logged when you make a purchase and somehow embedded in the files so Big Brother can track you if you mass distribute them. While I plan to only keep the music for personal use, it does somewhat creep me out that my info is being embedded and tracked in that way. This is why I never buy from the iTunes Store and instead import CDs I buy. But I would buy from the iTunes Store if there was a way to purge the files of such meta data. So...if I re-encode the audio (either in the same AAC or in MP3) will I be able to liberate my music of its meta-footprint?
