Music Library Compilation Albums are fragmented

It did not used to be this way and it seems like Sonos was working on a fix.  Just wanting to find out where that stands.  

 Maybe they will fix whatever is wrong.  I am not sure how that would exactly work because all my tags have Album Artist filled in.  How would they determine that the album is a compilation?  If the old app did your indexing correctly then there must be a way to do that without The Album Artist tag.  Got my head spinning.

In iTunes there is a box that is checked for part of a compilation.  Sonos used to recognize that and doesn’t.

 Got it.  Now I understand.  I have not used iTunes.

Some folk have suggested that this problem may be due to the latest Sonos firmware rather than the Sonos app. However, although I am experiencing the same issue (i.e. compilation albums now displaying as separate songs) when using the Sonos app, this does not happen when I view the albums using the Synology ‘DS Audio’ app (my library is on a Synology NAS).
   I wondered whether this might be if some interest, being that the Synology app displays all albums correctly while the Sonos app doesn’t, regardless of the Sonos firmware?

    Surely this would suggest the issue is with the app rather than the firmware?.

Same issue here and I refuse to edit my tags, I have  more than 1000 albums. iTunes and heos are working fine

 The reason I tag all my music files is to avoid exactly what happened with Sonos.  Sonos is not the only software I’ve encountered that does not react well to partially tagged files.  I never used iTunes or Windows Media Player because of the way they handle metadata.  I’ll take care of the tagging thank you!

 So stick with iTunes & Heos.

Thanks. Not detaching my collection.  Which Sonos had no problem with until recently.   Am interested in whether the team at Sonos is still working on restoring this capability.  Thanks for any info on that score.  

I reported this problem in July, case number ********, and  am still experiencing this problem with  compilation albums. Each track is displayed as a separate album. This makes it impossible to listen to any compilation album by selecting just one album. I have my music on iMac music. The only work around seems to be by access the music library via the folders option on Sonos and then the compilation folder. This problem has existed for several months. Please Sonos can you provide a more comprehensive response other than this is fixed for some and we are investigating? This is very unhelpful to those of us still experiencing the problem which I reported 4 months ago.

I don’t see why itunes cannot handle this as it should be, it’s using the Gracenote media database. Which seems legit/standard to me. Sonos should use the same options/info as before.
