Indexing NAS Library not working

This has been a problem since I bought my Sonos system a year ago. I have ca 500 albums on my NAS which equates to about 12,000 tracks. Many of these albums are combination albums with many tracks and all different artists. Sonos splits the album into individual tracks when searching under albums (that is ridiculous imo). Ok so recommendation is to equalise the artist names under, say, Various. I do this using  tag editor. Reindexing makes no difference. The original indexing is retained. I have tried removing the music library path and reentering. Still the same. I have tried removing all speakers from system and re adding. Just the same. How on earth is it possible to reindex my library? Where is this old data being stored? If I can delete it then it would have to take revised info from the NAS.

Make sure you don’t have a recycle bin / trash folder enabled on the NAS for this music share that Sonos can see.

If you are using the tags “Album Artist” = “Various” and “Artist” = the track artist for your various artist albums, make sure your Music Library settings are set for that. Look in Gear Icon (Settings) → Music Library.  You want “Group Albums By” set to “Album Artists” and View Contributing Artists = off. I also have “Sort Folders By” = Song Number, but that just applies to the Folder view.

Which  NAS?

Creating an empty share and indexing it, then switching back should work.

Depending on the tag editor you may have modification time stamp or recycle bin issues.

Make sure the recycle bin is not being indexed.

Where is the “View contributing artist = off” in the Sonos app? All other actions done.

I will try that. NAS is Qnap.

There are known issues with compilation album indexing and searching:

These are the settings.  My tags for compilations are Artist=( actual Artist ie “U2” )  Album Artist=Various Artists.  I do not use a Compilation tag.

I do not have the "View contributing artists" option on my app.

Are you using the Sonos controller on Andriod? It looks like that setting hasn’t “reappeared” yet on the android controller. Do you have access to iOS or Desktop controllers?

All that setting does is make sure the Artists listing isn’t cluttered with artists that are only on multi artist / compilation albums. Some people like to see them in the Artists listing. Others don’t. I fall in the latter group.

Have you tried what Stanley_4 suggested:

Creating an empty share and indexing it, then switching back should work.

That would force a rebuild of the Music Library index. If you are still seeing this problem after that, is it possible you are actually seeing this?:

Android! I fall into the latter group too. Some CDs have multi artists listed on a track so it makes it even worse. I have access to a desktop version so I will do it there. Thanks.

It would be nice to have the option to “Rebuild” the library similar how it’s done in a BlueSound system.  This would clear the data and start the index from scratch.  I occasionally have to do this with LMS ( Lyrion Music Server ).  Corrects most indexing issues.
