Regarding ID3 tags, is there any universal standard. ? From what i've tried so far, i don't think so, because if i add covert art in iTunes, and/or other meta data, it seems that only iTunes can remove them (or 3rd party products allow API access), with the exception of Covert Art. I've had issues with mp3tag in Windows, and also info was tagged in iTunes on Mac, mp3tag won't touch cover art or allot of stuff. Is ID3 tags unique for iTunes, or in general for the app your tagging them with ? If so, then that must make things more complicated.
