iPhone syncs custom lyrics every time i sync music (33k tracks)

iPhone 15 pro max iOS 18.6.2

iMac Apple M1 Sequoia 15.6.1 (24G90)

Every time i sync my music the custom lyrics re-sync (33K tracks) this adds a good amount of time to the sync as you can imagine, can't find anything that would cause this and it never used to do it.

Don't use work or movement etc etc so out of ideas

iPhone 15, iOS 18

Wow. My first guess was the work issue as I had this on my Windows PC with iTunes. I don't have 33+k files in my library but most of my Music files have Custom Lyrics.


I am about to switch to Music for Mac from iTunes Windows, and this makes me anxious, this issue would be a major setback if it would happen to me. (Not yet synced yet)


Hope there is a solution for this.

I have finally taken the plunge and synced with Apple Music on my Mac for the first time ever. A test of 6000 songs.


After the finished sync, I made some changes to songs, especially lyrics wise and also added some new songs


I then synced again and I must say, that it only synced the changed songs and the added songs NOT any of the others.


So fortunately this issue is not happening here.
