Is there a plug-in that will allow me to edit tags in audio/music files? I use iTunes and want to edit m4a file tags better than I can do with iTunes itself.
Only for WMA and MP3 files at the moment.
AFAIK, Apple don't document or provide a library/API for their tagging format so it's more work to support it. (People have worked out the format themselves, though. I'm thinking of writing a read-only plugin to display M4A tags, in addition to the existing dMCTags plugin. Writing a plugin that does editing as well is more work than I want to do, though.)
