Anyone with an iOS device will be able to reproduce the bug. It's been there since the first beta of iOS 5 and iTunes 10.5. Unbelievable!
Basically, either iTunes refuses to sync metadata changes to an iOS device or the iOS device refuses to accept metadata changes from iTunes during the sync. Metadata changes just won't sync. What kinda metadata? Anything from song lyrics, song genres to book authors, etc.
Here's how to reproduce the problem:
1. In iTunes, select any song for the experiment. Get Info. Paste lyrics.
2. Sync the song to your iOS device.
3. On your iOS device, go into the Music app. Find the song. Check the lyrics. They are there, correct? Good because the first sync always works.
4. Now here's the problem: go back to iTunes. Find the same song. Get Info. Edit the lyrics in any way (remove half of it for example).
5. Re-sync.
6. On your iOS device, go back into the Music app. Find the song. Check the lyrics. You expect to see the changes from the 4th step, right? Nope, you see the same lyrics from the 1st step, totally unchanged. Wait, but didn't you edit out half of the lyrics and re-sync?
7. Here's more: go back to iTunes. Find the same song. Get Info. Remove the lyrics completely.
8. Re-sync.
9. On your iOS device, go back into the Music app. Find the song. Check the lyrics. You expect to see NO lyrics because you removed them, correct? Nope, the lyrics are still there, unchanged, intact.
10. But do not stop here because it gets even more frustrating: this time you wanna remove the song, even the album, even the artist, even all of the music from your iOS device and re-sync the music with no lyrics whatsoever back to your iOS device. Alas, even after all this hassle, the very same song still has the very same lyrics from the very 1st step.
There is absolutely no way of removing or editing metadata after the initial sync. It's there permanently. It's like plague; you can never get rid of it no matter what you do: edit, delete, sync, unsync, resync, reset, restore, destroy the iOS device or even burn the computer.
