Hi caliskne,
Thanks for posting. I understand you're seeing some songs are not available in your region.
This resource has some helpful information: If songs are missing from your music library after you turn on Sync Library
If you can't find or play a song, check if you added it from Apple Music. If it came from another source, the song might be waiting to upload. Try these steps:
- Turn on your Mac or PC and connect it to the Internet.
- Open the Music app or iTunes for Windows.
- Keep the Music app or iTunes for Windows open so your library can finish uploading.
If you see an ineligible icon next to a song, delete the song, then add it back to your library. If you still see an ineligible icon next to a song, then that song can’t be uploaded.
If a song is grayed out, then the song might be waiting to upload, no longer available, or not yet released from the Apple Music catalog.
Make sure that all of your devices have Sync Library turned on, and signed in with the same Apple ID.
If you’re still missing a song that you added from the Apple Music catalog, then the song might have been removed from Apple Music or is available under a different file name. Try searching Apple Music for the song, then add it to your library."
As suggested above, try searching for one of the songs in question and see if you can re-add it to your library. Does that help?
If not, you might use this link to verify that the songs are available in your region: iTunes Link Maker
Cheers.
