I have a number of songs where Sonos does not recognise the artist from the field in iTunes, and some more where it doesn’t recognise either the song name or artist - in which case it just shows up as a file name in the Sonos playlists.
Good examples below - two tracks from the same artist, Avicii (may he rest in peace). As you can see the set up in iTunes is identical - yet in Sonos, for one track the information is received fine, but not recognised at all for the othr.
Thoughts/comments/suggestions?
