I have about 20,000 mp3s in my music library.
These are stored in folders as ARTISTNAME \ ALBUMNAME \ TRACKNAME.mp3
Many of these are classical pieces where the actual ALBUMNAMEs and TRACKNAMEs may be identical across multiple Albums. For example, I have 16 versions of Bach's Goldberg Variations by different Artists. Each ALBUMNAME for these 16 is identical. And within each Album folder, the 32 TRACKNAMES follow exactly the same naming convention. I have catalogued the metadata for each Album's 32 Tracks to an identical standard over many years.
Every other media player software I use (principally foobar2000) understands this and provides me with 16 unique Albums, one per Artist, regardless of whether I sort by Album or by Artist.
When I ask SONOS Music Library to display this under Artists it understands that each Artist has one Album with 32 Tracks. So I can successfully play the complete work. However, when I ask SONOS to display this under Albums it doesn't show me 16 Albums and allow me to choose which one to listen to. It takes all 16 x 32 tracks and tosses them in to one Artist + Album display, (I think it just happens to be the first alphabetic Artist) and I get 16 Track 01's, 16 Track 02's, 16 Tracks 03's etc. Hopeless for selection and listening.
I'm reluctant to undo a naming and tagging convention that has worked well over the years in other cataloguing software, tagging software, and playing software. Any suggestions how I can encourage SONOS to take account of the fact that the same Track by two different Artists shouldn't be arbitrarily, and wrongly, lumped together?
