queue continues to grow, automatically

Same issue here; it’s very maddening.  Been going on for months, but it reached exhaustion over the holiday when my family was trying to queue up holiday music. 

I have now found the only ways to deal with trying to go to from a playing YTM artist station with enormous queue is either play an individual song from a different artist or completely erase the cue using the  trash can symbol in the top right corner.. only then will you be  'allowed' to leave that one streaming station. 

I am thinking the same thing. This issue has been going on for way too long.  The play queue is such a basic thing in this product to not have it fixed for this long.  This should be a huge shame for sonos!

Having too many sonos speakers at home is a significant cost for me to simply toss these out and switch.  The only reason I held out on buying more sonos products last few months is the sketchy software that we have no choice but to use with these speakers. 

I am now thinking it may be time to cut my losses and ditch these for a different product that don’t have full dependence on such lousy closed proprietary software.

I just ran into this issue. I’ve been using YouTube Music to play a “brown noise” album overnight for the past few weeks. It is basically an album of repeated tracks with no gaps. Today my Sonos system ground to a halt and I couldn't play anything from any of my music services, only radio stations. After about an hour of tearing my hair out I discovered I had a queue of more than 26,000 tracks. When I deleted the queue, everything returned to normal.

Add this to my list of Sonos garbage. I used to enjoy Sonos. No longer. Just another in a long line of things that never get fixed, according to what I just read in this thread.

Just keep telling them you won't buy any more hardware till they fix the app.

Please contact support and let them know about the issue as in another thread the Sonos rep indicated that they won’t fix it unless they get more complaints. 
 

I used the chat option and it only took about 20 mins. 

I’ve examined the same issue but with a total of 64815 songs…

Fact is (as per 24. Feb. 2025), when you start playing tracks from a folder (in my case NAS) using the S2 App (IOS), the list populates up to 64815 tracks…

Workaround: start the folders music by using the desktop App! Do not touch the S2 App!

After done, the S2 App will show/play the correct amount of tracks.

Same problem when playing my Music Library from a NAS.  I have fewer than 10,000 tracks in the library but the Sonos app (Android) shows 60,000+ songs in my queue and will only play a small number of them on shuffle.  Please fix this Sonos!

Also dealing with this problem playing from my Synology NAS.  Part of the issue was the NAS saving ‘snapshots’ in the shared folder that Sonos could see and load multiple duplicate tracks in my library.  Removed the snapshots and now the library only shows my 18,000+ tracks but I still can’t save the entire library as a single playlist.

Playlist saving is not a feature of the new app. You can do this with the desktop app however.
 

The desktop app also doesn’t suffer from the growing queue bug. Add the playlist with the desktop app and control playback with the mobile app.
