Hello ​@PearlMikeJam, welcome back!

I am sorry to hear about the issues you’ve been experiencing in regards to your Music Library and Music Library playlists within Sonos.

After having some issues with my music library playing playlists with more than 100 songs, I decided to delete it and add it back (before I discovered the playlist limit is a known issue).  It had been so long since I added the library, I had issues adding it back.

As it has been mentioned in your other thread below by another Sonos Community moderator and as you said here, this is a known issue which we are working on a fix with no ETA for it.

I have discovered a couple issues.  First, I can only add the Public folder from the NAS.  I cannot just add the Public/Shared Music Folder.  Are subfolders supported?

Have you tried moving your Shared Music Folder at the top of your NAS drive, along with the Public folder and attempt to add it then?

The other issue is the library is creating multiple of the same playlists.  I only have .m3u playlist files.  I suspect it is reading the playlists in the iTunes library.  I have backup copies of the library in other folders which would explain why there are several versions of the same playlist.

If duplicate playlists exist in the library, it means Sonos has found multiple files containing the same playlist in your shared music folders.

I would suggest you to Submit Diagnostics and reach out to our Support Team. They have tools at their disposal to provide you with advice and information, specific to your Sonos system and what it reports.

I hope this helps.

Thanks ​@Sotiris C. 

To bel clear, I know there is a known issue with the apps limiting the number of songs that will play from a playlist.  I was just giving some background.

I cannot move the music folder.  It will create issues with other apps.

There are not duplicate playlist files.  That is the confusing part and why I speculated the app could be reading the playlists in the ild iTunes Library backups I have.  The Shared Music folder has the playlists in that folder with all of the songs related to them in subfolders by artists.

I can submit diagnostics.  I was hoping to understand why I cannot add just the Shared Music folder instead of having to add the full Public folder.  I have seen others mention it in posts but there does not seem to be an explanation.  Not clear if it is because of the two word folder name or if subfolders are not supported defining a music library.
