Files are greyed out after syncing iTunes Library to iPhone

Once hypha subscribe to Apple Music, you should not have to manually "hard-wire" sync your music library to your iPhone. You should be able to access your music library, including your playlists, on any device that has the Apple Music app and signed in with the same Apple ID that you use with your Apple Music subscription. Make sure you have Sync Library enabled on all your devices:

Hi,

You don’t need an Apple Music subscription to use the music app on your computer or iOS device. You can play your own music on your computer and sync it to your iPhone. See Sync your device using your computer – Apple Support (UK)

There seems to be an occasional bug where a sync operation doesn't complete properly leaving greyed out tracks on the device when viewed in iTunes which either aren't displayed on the device, or won't play, and don't get replaced during a subsequent sync.

Try removing all music from the phone (Settings > General > iPhone Storage > Music > Edit > Delete All Songs) then try syncing again. If that still doesn't work try the comprehensive approach in this post on erratic syncing.

The same behavior started recently for me. I have iTunes ver 12.13.1.3 on Windows. iPhone iOS is ver 17.3.1. I do not use Apple Music. I have no idea how to get that working again. It worked for correctly for year.

I am sorry, are you saying that people like myself who do not use Apple Music and avoid DRMed music and only have offline music that they own, can no longer use the Music app to play that music on their phone?

I have been trying to accept Apple's increasing limitations to the music app, and this is certainly a step too far.

I am not interested in sharing my music with Apple so this is certainly not an option.

It is really sad to see that we are at the end of an era. I understand I am an edge case of an edge case but still sad that the couple of terabytes of CD's and records I have can no longer be managed by Apple Music.

I was able to correct this using a different cable (as indicated in other posts I found). Sync did work as expected afterwards.
