iTunes 12.5.3 crashes constantly on macOS Sierra

I have the same issue, iTunes 12.5.3.16.

I was adding songs and chaning artwork to other old songs.

iTunes started to crash.

I start again, and I see new songs duplicated but not uploaded on iCloud.

I start to sync iCloud music library and iTunes crashes when upload songs.

I don't know what to do. I logged of and log in again, but with no good result.

I'm seeing the the same/very similar problem.

Updated to 12.5.3 last night - this morning, if I add an album (files on local drive) the album tracks are duplicated, but not added to iCloud.

If I leave iTunes for a few minutes, it crashes. This has happened maybe half a dozen times in the past hour.

Since I logged off, now I have no chance to use iCloud music library (iTunes match). Every time I log in, started with sync and crashes during upload of some songs, but I don't know which.

So sad.

Same problem here - reinstall doesn't solve the problem.

Same problem here on 10.11.6.

"Quits unexpectedly" constantly, even if app is just sitting, not playing music. All started after this mornings update.

Hope this gets resolved soon, because iTunes is completely unusable at this point.

Same issue here. And it's seems random (and is incredibly irritating)

Same here. Late 2012 iMac with the latest MacOS release. It started after I tried to add a new album. Crash, crash, crash, crash, crash all morning with no way to stop it except leaving iTunes closed. it's completely unusable now.

Exactly the same problem here. Updated to iTunes 12.5.3.16 this morning on two Macs running El Capitan. Both crash when adding an MP3 file to the library (and ultimately iCloud Music Library). I get the duplicated file upon restart. The only way to prevent crashing is to delete the file(s).

I even tried to convert the MP3 to M4A using iTunes > Convert > Create AAC Version. The new file converts fine. I delete the original MP3 and try to add the new M4A. Still crashes.

For me this doesn't work.

I logged off too. And now it would upload all songs. But it crashes after some minutes.

I don't know which song create this problem, so I don't know which song delete.

Anyway, I can't see songs stored on iCloud but not downloaded locally. I can see them only from other devices.

Are you on a Mac? If it works for you, I'm wondering if this would work on a PC. I'm running Windows 7, Home Premium, 64 bit. So far none of the suggestions have worked for me about getting songs to my iCloud Music Library.

Same problem. I hope they fix it soon.

I have the same issue. I started the iMac, ran the updates and iTunes was one of the updates. I started iTunes to add some songs and it just crashes over and over. I have tried at least 20 things to fix this.
