I just bit the bullet and updated my Mac OS from 10.14.6 to Monterey 12.4.

Importing my old iTunes library from the xml file worked fine...mostly.

The problem is, I had a ton of TV shows, movies, and audiobooks. In the old iTunes, they were all correctly tagged with the proper media type.

In the new "Music" app, when I go to "get info" and find the "media type" dropdown, there is exactly one entry that I can select. It's either "music" or "music video" depending if the selected item is an audio file or a video file.

Needless to say this is a MAJOR regression, and also makes shuffle completely unusable as it will shuffle in all tracks from all audiobooks along with all songs.

How can I fix this? Is my only option to delete all the audiobooks and non-music videos from my "Music" app library? Or is there some hack I can use to correctly identify non-music media files while still having everything in the one app like the old iTunes app?

Incidentally I also haven't yet attempted to sync my iPod Touch (last generation) with my computer; I don't know how that will go. Links or advice welcome on this point. Not the end of the world if I can't sync TV shows, movies and audiobooks to it anymore, but it will probably push me away from Apple devices for the future.
