Adding a Custom Tag to an Entire Library
I need to add a custom tag to my entire library of FLAC, ALAC, AAC, and MP3 files. Let say the tag name is "XYZZY" and the initial value needs to be set to "0" (zero). What would be the easiest way to add this tag to every file in a recursive manner. Please provide examples if you can.
