The blank playlists and greyed-out songs are classic symptoms of an iCloud Music Library/Sync Library mismatch that often happens when changing Apple Music subscription plans. Here’s a targeted approach to fix this:
Root cause: Switching from a Family plan to an Individual plan can cause iCloud Music Library to re-evaluate which songs are matched/uploaded vs. purchased, which can grey out unmatched tracks.
Step-by-step fix:
1. On your MacBook Pro:
- Open Music app > Music menu > Settings > General tab
- Uncheck "Sync Library", click OK
- Quit Music app completely
- Wait 30 seconds, reopen Music
- Go back to Settings > General > re-enable "Sync Library"
- This forces a full re-sync with iCloud Music Library
2. If playlists are still blank on Mac:
- Your Mac’s local library may be disconnected from iCloud Music Library
- Check: Music > File > Library > Update iCloud Music Library
3. For greyed-out songs on iPhone:
- Greyed songs on iPhone usually mean iCloud Music Library cannot match or access them
- These are likely songs uploaded via the old library that didn’t transfer properly after the plan change
- On Mac: select the greyed songs in Music app > right-click > Add to Library (to ensure they’re in your local library)
- Then File > Library > Update iCloud Music Library
4. As a last resort:
- Disable Sync Library on all devices
- Wait 24 hours
- Re-enable Sync Library on Mac first, let it complete, then on iPhone
This should restore both the playlists and the greyed-out tracks.
