Here's my situation: I'm setting up iTunes for my wife (she just doesn't like Winamp) and I want to be able to create smart playlists by filtering on the actual filename. I have all of the ID3 tags updated (to a ridiculous level of detail) and plan to continue to use MP3Tag to manage my library.
- iTunes doesn't allow you to search the filename
- I want to update iTunes 'Grouping' field (ID3v2.3 TCOP, MP3Tag CONTENTGROUP) with the filename including the file path and search on it.
- When I update the 'Grouping' field within iTunes for an M4a track imported using iTunes, MP3Tag does not see the CONTENTGROUP tag (nor any tag containing the test data), however when I make the same update on an MP3 ripped using Winamp it does see the correct tag.
-Likewise, an edit to the CONTENTGROUP in MP3Tag on an MP3 shows up in iTunes, while an edit to the same tag for an M4a in MP3Tag does not show in iTunes.
What am I missing?
