app updates have duplicated music library albums and lost some tracks

Similar problem that affects (so far) only latest addition to my Sonos library: A new double album I just bought in iTunes (on Windows 11) displays as 12 albums in my Sonos S2 controller, each one with the 14 tracks listed in the same scrambled order. My Android Sonos controller shows the album exactly the same way - duplicated and with the tracks scrambled.

All metadata is in order as far as I can tell; tracks show disc # and track # since it’s a 2-CD set.

My PC file system shows the album as a single folder. It appears as a single album in iTunes and in my MediaMonkey 5 music player.

My Sonos Windows controller is up to date: Sonos S2 version 16.3, build 80155014.

The Sonos support bot mentioned that “a Sonos music library has a 65,000 track limit.” My library has 8357 files (tracks) according to the MediaMonkey library listing.

I bought and downloaded another album today, partly to test whether the problem I reported yesterday was a one-off. It was not.

The new album shows in my Sonos library in two identical copies, identically scrambled:  track numbers run 1-6-2-3-4-5, no problem for me since tracks 1 and 6 are standalone pieces while 2-5 are a set.

Sonos happens to list today’s tracks in alphabetical order but yesterday’s album tracks are not, so that doesn’t seem to be what’s happening.

I have to assume that the most recent Sonos update is causing this problem as it’s never happened before in years of adding albums to Sonos.

 If the Artist tag & Album Artist tag are not exactly the same 16.3 screws it up.  I normally tag compilations with the performer for the Artist tag & Various for the Album Artist tag.  So my compilations are a mess.  Hopefully Sonos will fix this soon.

 I learned long ago to match Artist & Album Artist tags ( with the exception of compilations ).  Makes it easier to find the artist you want.  This is very important for classical albums where the default tags are all over the map.

I also have the problem. This is 100% a Sonos issue. I have the same library connected to my S1 system and it’s fine. No dupes, no missing tracks. The same library that I have been using and adding to since 2006. 
 

Last man / woman out please switch off the lights. 

I have same issue, using 16.4 beta windows 11 and android app. so no fix as of yet

Yes, thanks for your reply. On further investigation it looks like there may have been an issue with some file corruption during a power outage around the same time that created a few 0kb files. Good news is I had backups and now a UPS on my server. Unfortunately it came at the same time as the Sonos issue with the library. So in this case Sonos weren’t responsible for the 0kb file issue. Well apart from all my compilation albums now having loads of individual albums. Thankfully I’ve been able to get round to using the folder option which is not ideal but does allow you to play compilation albums in one piece. So in this case, sorry Sonos (bet they don’t see that often). :-)

joining this thread - FINALLY got my NAS reconnected and now this issue. Following for a fix. 

Sonos truly used to be a SUPERIOR system and my set-up was killer. What a massive let down this last year has been. 

The Sonos firmware programmer must be on holiday, or quit...😎

This issue has been a problem for many Sonos customers since July. No idea why a fix hasn’t landed yet???

Seriously, it makes me wonder how big their development team actually is and whether they understand the code base they are tasked for changing. My guess is that the original developers are well gone and the current bunch are simply not up to the task. Prove me wrong….please!

If it helps I have Blue Sound for my living room and this works with compilation albums superbly, however after latest update Sonos has royally screwed up all compilation albums and no amount of fiddling with Mp3Tag will fix it.

So Sonos, is this ever going to get fixed? I spent approximately £7000 on our Sonos music system, and for the last few months have been unable to play a large percentage of albums from my music library, I think because of this bug. The fact that it updated in the background to something completely broken makes it feel like consumer lawsuit territory, especially combine with the app debacle. Come on, just get it fixed 🤬

I experience the same problem. It used to work as expected a few month’s ago - no “multiple duplicate” albums. Appalling software/firmware from a company that I no longer trust.

You can fix this providing you are happy to forgo searching by artist or composer.

Download Mp3tg, open the folder on your disk, select all tracks, copy the Album Artist into the Artist and Composer field, save and then re-index your music library in Sonos.  Don’t put blanks in the Artist and Composer fields, which I also tried, for some reason Sonos doesn’t like this and won’t play them.

Sonos has fixed the Music Library Compilation issue with the latest Firmware Update 16.4.2.

Thanks for the heads up, I can confirm for my system it looks ok. What a relief!

Hopefully they will update the way albums display. I preferred the old way of slightly bigger images in a grid formation.

Not for me, after reindexing, still the same

Changes have been made but not documented…

I have just over 200 compilations which were ripped in iTunes long ago and without the Album Artist field. These albums displayed and played perfectly until they screwed up the Firmware.

Sonos seems to have dropped indexing “iTunes Compilation” but it was quick adding Various Artist to all the tags this morning.

Slight improvement- but in no way is this fixed. 

Sonos are still working on this issue. It has been fixed for many users, but as you are finding it is still an issue for some.

Ross.

Albums are still duplicated on my system after updating to 16.4.2  and updating the controllers to the latest versions on on IPad, Android and PC.

There has been no apparent change or improvement on this issue on any of the interfaces. 

 For compilation albums make sure your Album Artist tags is Various Artists.  Your Artist tag should be the actual performer.
