Music Library update does not update all tracks in the library.

Hi @jonblauch, thanks for reaching out and for sending a diagnostic report of your Sonos system. As I check the report. It shows that there are 5700+ tracks in your music library. I want to ask further questions to check on this issue. 

• How many total songs do you have in your Music library?
• Did you change PC/Mac or laptop before this issue happened?
• Are you trying to update it on a Mac or windows controller?
• Are there any changes made in the music path folder for your songs before this issue happened?
• Kindly check this article about Updating your Sonos music library for reference and some troubleshooting steps.

Let me know your thoughts on the advice above.

1. There are about 9k files in my music library. THere does not seem to be any logic to what is missing. Some entire albums, and some .flac files ( concert downloads)
2. No changes to my PC or underlying library.  I moved my library to OneDrive ( Yes,  I have a windows PC), and then realized it needed to be on my PC, so moved them back. That is when I removed and reinstalled my music library
3. I have checked that article and see nothing there i have not tried

Did you look at the diagnostics I submitted>
