OK let me add some detail.
Current setup: Using a MacBook with Music.app organising all my files in the MacOS Music Folder.
I would like to move all files/library (playlists, ratings, play count etc) to my PC.
I have already tried copying the Music folder etc, but importing the Library is proving difficult.
Right now I am trying to do it via Exporting the XML Playlist (on Mac), and importing it on PC (but it requires a lot of editing to the XML since things like %20 is added into each file name, the slashes are reversed etc).
I literally only have my MacBook for Music - but since Catalina and the whole Music.app thing I have lost Artwork, Music.app has butchered my files (added a 30s repeat to the end of each song), and most recently, duplicated every single song when synced to my iPhone.
