If you rename the album cover file to “folder.jpg” and place it in the specific album folder, the correct album cover should appear in the Sonos app. Be sure to “Scan for New Content” in the Sonos app after you place the file in the folders.

Or you can embed the album art within each track.  I use Mp3tag to do this for all my album art.

Thank you, GuitarSuperstar, for responding. I looked at the link you recommended and am not sure I understand it. When I ripped my CDs into my shared file on PC using EAC, they did not rip into separate folders for each CD. All the files created (flac, jpg, cue, m3u8, log) for each CD are contained in my PC Music folder that is shared with my Sonos Music Library. They are not in separate folders for each CD. Should they be?

Yes, ideally each album should have its own folder with only the specific album’s tracks in that folder. The root folder should be the artist name. Here is an example:

Notice the “folder.jpg” file contained within “The Wall TRemaster] eDisc 1]” folder. This is the album art file.

Wow! I am going to organize my Music folder and try to match your example. And the jpg file is actually just named “folder.jpg”. This should all make a difference. After I make the changes, I will post the results. Thank you very, very much.

Hi –

I organized the files into folders and changed the name of the jpg file to folder.jpg and everything appears to be working properly. Normally I would have organized the files that way, but this was the first time I ripped CDs to flac and was using a recommended program called Exact Audio Copy (EAC). Google searches seemed to agree that EAC was the best and easiest program for ripping CDs to Flac. It is a complicated setup and after ripping it produces jpg, log, cue, m3u8 files along with the flac file. It does not put the CDs into folders. Now I find out that Windows Media Player easily rips CDs to flac and puts them into proper folders for Artist and Album. Just did one now, scanned my Music Library for new content, and everything worked perfectly. All those other files EAC creates are unnecessary of the Sonos Music Library. Possibly there is more error checking with EAC, but Windows Media Player worked just fine for me. Thanks to GuitarSuperstar for showing me an example of how files should be organized in the Sonos Music Library, and letting me know that the jpg file needs to me named folder.jpg. This was my first time ripping CDs to flac and creating a Sonos Music Library. If I had not used EAC and used  Windows Media Player, the extraneous files would not have been created and files would have been organized in proper folders. Then all I would have needed to know was that I needed to put my album art into the album folder with a filename “folder.jpg”. Really appreciate your help. Thanks.
