And its the same songs across multiple playlists that have this issue. If I play this song directly within Sonos App from the 'Song' directory it works fine, its only when its part of an Imported Playlist created in MusicBee that the song cant be found. This is true of every song in the library and in the playlist, but somehow for a select few of them it omits the subfolder names and is looking for them directly in the MUSIC folder and therefore not finding them. And that message is correct - the song is not in the MUSIC folder, it is in a subfolder within the Music folder, based on the name of the artist. And when I get the error message it will say Unable to Play.DESKTOP//MUSIC/SONG NAME not found. This song is in the Music Folder on my PC in the same place and format as all the other songs on the playlist which DO play correctly. These tracks will not play - when the playlist gets to them the message says 'Unable To Play.DESLTOP/MUSIC/.Long Filename.Could Not be Found'. However certain tracks are showing as an. When I create a Playlist and then open the Sonos Desktop App and Update Library, I will see the playlist there. They work fine on my desktop and also when imported into my phone (I use GoneMad app).

I create my playlists as M3u files in MusicBee.

I dont know if anyone has a solution to this but so far Sonos support cannot figure this out, so I thought I would see if the MusicBee community might have ideas.
