Hi Jdawgggggggg,
We see you're having some issues with some songs not showing up in playlists in Apple Music, and we'd be happy to help work on that.
Which device are you using Apple Music on? We noted you've posted in the Apple Music on Android section, but we just want to ensure, so that we can provide the best steps to take.
Does re-importing the songs to the library, or re-adding them to the playlist seem to help with having them visible? It sounds like they're still present, as the song does play.
If you're indeed using Apple Music on Android, try some of the following steps:
-Clear the app cache:
From the Home screen, tap Apps.
Tap Settings.
Scroll to Apps, then tap it.
Tap Apple Music.
Tap Storage, then tap Clear Cache.
Return to the Home screen or the application list, and reopen Apple Music.
If it persists, try turning the device off for 30 seconds, and then power it back on, and see if that's helped.
Take care.
