Ok, so after much trial and error on this, I have finally found the solution.
My set up is as follows. My music library is on a NAS which is connected to a MacMini (running Sonoma 14.2.1) . Every time I re-import my Apple Music Library, it does not bring over the playlists.
Here’s how you do it.
- Import music from your NAS (or even external drive) into Sonos
- A new file will be created in the music folder in your home folder (~/Music/iTunes/iTunes Music Library.xml)
- Move that iTunes folder (and the file inside) to where your music is stored.
- Remove and re-import your music library in Sonos. Sonos will pick up the itunes .xml file and import the playlists as well as all the music.
I do not think you can simply “update the music library now” to bring over new playlists. The file containing the playlists is only generated when you do the first import. I don’t think it’s updated at all.
If there is a better solution out there, I’d love to hear it.
