List of available music metadata fields, migrating from Apple Music/iTunes

[JANONYMOUS]

Hi,

I was wondering if there's a list with all the available metadata fields for Jellyfin Music.

The following is what I'm essentially using in Apple Music:

• Album
  
• Album Artist
  
• Artist
  
• Comments
  
• Composer
  
• Disc Number
  
• Genre
  
• Grouping
  
• Track Number
  
• Year
  

Which of these fields will be adopted by Jellyfin after all?

As far as I can tell, Album, Album Artist, Artist, Disc Number, Genre, Track Number, and Year seem to be there.

Now I don't care about ratings or stats, including plays and skips, but I heavily rely on Comments, Composer, and Grouping.  Unfortunately, I can't seem to find those fields or possible equivalents in Jellyfin.

Am I missing something, or do these fields not exist in Jellyfin?  If so, will more metadata fields be made available in the future, and will they take over the respective values from Apple Music?

Thanks for your insights!
