Syncing iPhone X from Catalina syncs ALL my music every time, taking ages

I've only recently upgraded (I use the word loosely) to Catalina.


Now, every time I sync my iPhone X - for example if I have added a couple of songs to the Music app on my iMac - it copies every song from the iMac to the iPhone, taking ages.


With iTunes it just used to add the new songs to the iPhone X and so syncing only took a few seconds.


Why is this happening and how can I make it just copy the updated songs/info to the iPhone, not every single thing every single time?

iMac Line (2012 and Later)

Hello BlueberryiMac.


Welcome to Apple Support Communities. We understand that when you sync your iPhone to your Mac that it syncs all content again rather than the most recent updates. We’re happy to help.


Please try the steps in the section titled “Manually add content from the Music app or TV app” here: Manually manage content on your iPhone, iPad, or iPod touch using your Mac - Apple Support


If you don’t wish to manually manage your music, please use the steps here when syncing: How to use safe mode on your Mac - Apple Support


We also recommend syncing in a test user account here: How to test an issue in another user account on your Mac - Apple Support


Let us know the results.


Take care.

OK. It says this:


Add content from the Music or TV app

  1. Connect your device to your computer.
  2. Open the Music app or TV app on your Mac.
  3. Select the content that you want to add to your device from your library.
  4. Look in the left sidebar for your device, then drag the content to your iPhone, iPad or iPod touch.


What if I purchase a new song from the iTunes Store on my iMac and I have dragged it into a playlist in the Music app on my iMac... How do I make sure that newly purchased song goes into the correct playlist on my iPhone, if I am simply dragging the new song from the Music app to the iPhone icon in the Catalina sidebar?


I do not stream songs using Apple Music. I prefer to buy them and I like to have them in identical playlists on both my iPhone and iMac.
