Just discovered that mood tags exist. I find that fascinating to add such tags to my music library and then have automated playlists created for each mood tag.
So far, so good - but what I don't get is, how mood tags are utilized in audio players. Using iTunes, Plex and Kodi. I don't understand how I can work with the mood tag in any of them. iTunes doesn't even seem to be showing the mood tag anywhere in the file, neither does plex (didn't check kodi). So I guess my chances of using that tag to then create playlists are zero?
This might be a very stupid question, but currently I am stuck and would be thankful for any further insight into this topic / question.
If this turns out to be usefule, I guess the follow up question would be, can I effectively tag my entire music library with mood tags from last.fm (or musicbrainz if it supports "mood") without touching any other metadata or changing any album art. Every other setting should stay untouched. I would hate to loose a few years of work.
