[iOS 11] Music app: "Unknown Album"/No Artist/Year/Genre info for majority of song library
Hello, I have an iPhone 6S+ running iOS 11. My problem is that for some reason, my Music app can no longer sort songs appropriately. It says many of my songs are from Unknown Album. It has split up whole albums - 5 tracks on the album will have the correct artist and album name but for some reason, 2 or 3 songs from that album will suddenly come up as Unknown album, with no artist name, and no year. This problem is not consistent - some songs have been stripped from all data except the song title or genre. My whole Music library has become a mess!
My iTunes library on my Mac is still fine. Everything is cleanly organized and songs are sorted correctly. I don't have a single song in my library listed under Unknown Album. I tried wiping my phone's Music library and resyncing my music, but its just made it worse. Attached are screenshots - I'm having a hard time explaining the issue bc it's just so inconsistent and bizarre.
(Sorry the screenshots are so big.) Some people on the forum with a somewhat similar issue said to alter the artist name/album name in iTunes. That's doesn't help and I have 3k songs, I can't do that for every one. Any ideas?
