apple music memory leak

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.

Just wondering what to DO with all that music. Any song can be found somewhere on the internet these days, so there is hardly any use to keep them on your computer. And having the time to listen to all this music (that's what it's for, isn't it?) seems impossible to me.


But this was just a thought when I visited this page. There are more important issues to be discussed here, so let us stick to those. ;-)

I know what you mean...

But I’m a music lover, I like to own my music. I like to own my records and my digital files (that I also have in the cloud with my iTunes Match subscription). That way, I don’t need to subscribe any streaming service. Why should I? Besides, I have lots of music that isn’t available on any streaming service. ;)


If I have the time to listen to all my music? Of course not. And, believe me, I listen to a LOT of music, it’s my passion and my job. But that’s not the point...as any music geek could tell you ;)

Worth noting the same thing happened to my movies but only approx. 10 of 879 have missing artwork, both iTunes store purchases and backups of BluRays that I own. All of my TV Shows retained the artwork. Both Movies and TVShows blasted through in a matter of minutes with no memory leaks, so clearly it's just Music that has a problem.


I'm also pleased to report my playlists have remained intact, which was an issue with iTunes following an upgrade in the past, so they have at least nailed that one.

Same here too. Once I start playing something in Music it can continue happily playing forever, but if I want to change anything - wake the screen from darkness, open another app - the track playing gets incredibly glitchy and won't close for 10 minutes or so, while it works through whatever it is doing. I can't even see what is going on in Activity Monitor as all of the memory is being used up by something - presumably Music as it is the only thing really running. This is ridiculous!

Even having left it running alone with no music playing for hours at a time hasn't cleared the backlog of tasks. OK, I've got 400GB of music for it to sort through, but at present this app is useless and making my machine unworkable in any other capacity.
