Songs not showing up in sonos app

Are the new tracks from the same source as tracks you have previously added successfully?  I just wonder if there is metadata missing or wrong so that they are failing to show up or are showing up as “Various” instead of under the Artist name, for example.

Or, possibly, have they been placed in a different ‘folder’ than the normal music folder? Sonos doesn’t have the capability to look in other areas on your Android device. 

THanks for the reply.  I've checked, they are in the audio files section. I also discovered that some of the songs just have static, even though they play fine through the phone and are downloaded as mpegs.

Are they songs you’ve purchased/ripped or downloaded as part of a streaming service?  I believe tracks you’ve downloaded as part of a streaming service can only be played through the streaming service app.

All my music is ripped, but I've never had an issue until the last 12 songs wouldn't show. The new playlists I had made in samsung music also won't show.

Have you taken a look at the metadata yet?

It's not a compilation album?

Were they ripped with the same software as previously?

Yeah I downloaded them from the same website. It's not a compilation album. They're format are mpegs. All my songs are in the Audio file, but sonos won't find the last 12 songs I downloaded.

It is possible that the bit rate of those .mp4s is not supported. Not all .mp4s are created the same. Take a look at the supported audio formats FAQ.

Thanks. I checked and they're downloaded as mp3s. The tracks are all identical to the older songs I downloaded that work. I also tried to do the scanning of the music library, but it doesn't seem to work either. 

As shown on that link I provided, there’s a limit to the upper end on bitrate on .mp3s as well. You can insert any format name into that post. .mp3, .mp4, while they’re all slightly different, each has a possible limit to what Sonos can play
