BTW, there was a variant of this discussion with the iPod and mp3 players back then. Some people wanted to manage music "by hand" in the file system, and had various schemes for doing so (folders for genre, then artists, then album, etc.), and wanted that reflected 1-to-1 in the mp3 player.
iTunes (and the iPod) had a different idea: The app takes care of file management, and you have a frontend supported by a database containing all sorts of metadata to browse your music (both static metadata (artist, genre) and dynamic (play count, skip count, last heard)). iTunes has smart playlists which I love (all songs with 3 stars or more that I haven't heard in 6 weeks).
I'm firmly in the latter camp, and similarly prefer Jellyfin over a pure SMB share for movies.
