Any files that you purchase from iTunes (or obtain with iTunes Match) will contain your personal information:
Is there a script that automatically goes through all music inside the iTunes Media folder and anonymizes
.m4a (iTunes AAC) files to EFF-standards?
While also meeting the following requirements:
- Not trans/re-encoding (and thus losing quality)
- Keep the same file format
- Keep play counts, import date, etc.
- Keep songs organized in playlists as they are
I have thousands of purchased iTunes songs, so going one-by-one is not an option.
