I've just upgraded to Catalina and started using apple music. Even while idle (aside from "loading artwork" which I'm guessing is a result of switching from iTunes to apple music) I'm seeing the RAM constantly increase. I just checked the performance monitor and sae apple music using 86GB! I've restarted the application and I'm monitoring now and can see it constantly rising.
It does seem like the album artwork sync was the issue. I ended up deleting a 4GB folder of "album artwork" from my iTunes folder. This retained all artwork that was embedded in music files but I've lost a lot of other artwork which I'll just have to reimport. I can say though that since deleting this folder the sync notification has gone and iTunes now doesn't use more than about 1.6GB of RAM.
I had the memory leak issue. I force quit Music, but it still said my system was out of memory. I reboot it, started Activity Monitor and Apple Music app. The status bar says loading artwork and the memory is up to 5GB now.
My artwork folder size is 5GB.
My iMac has 40GB RAM so it will take some time to fill up.
I will update this thread after I see if it crashes or not. Post how much memory Music was using if you can capture it.
Where did you move "Album Artwork"?
I quit Apple Music app when it reached 11GB. It was showing no signs of stopping, I'll try making a copy of my Artwork folder and the deleting it from the iTunes folder.
