I'm new to iCloud, having decided to try an Apple Music subscription when I received my HomePod speakers. As a result my iTunes library, which is quite large, is now being uploaded to the cloud. There are a couple of things I'm unclear about: - uploading my library to the iCloud music library will take a fairly long time, I'm sure. In the meantime if I try to quit iTunes, I get the message: "Your music is being uploaded to your iCloud Music Library. If you quit now, your upload will be cancelled. Are you sure you want to quit? What this seems to mean is that I need to keep my computer on and iTunes open for as long as it takes, potentially days if not weeks. I did quit iTunes once during this process, thinking that surely it would be able to resume when I reopened iTunes, but I'm not sure that is what happened. I would appreciate it if someone knowledgeable could clarify this. - once I have my own music library uploaded to the cloud, then from a practical standpoint it is all available to me whether I'm at home or elsewhere, and using any of my devices - iPhone, iPad, etc. So what is the real difference between this, and iTunes Match? It seems to me that either one will accomplish the same thing, which is to make your own personal music library available to you via the cloud. - I'm also hoping that going through this process of uploading my library to the cloud will not result in any changes being made to how my music has been painstakingly labeled and organized within my iTunes library. After taking so much time to edit the labels in various fields so that my music is consistently labeled and can be easily sorted and searched, not to mention making sure that the album artwork is correct for each of my albums, I sure do not want to lose any of that information. I am trusting (fingers crossed) that regardless of whatever is uploaded to the cloud, my iTunes library will remain unchanged and as I have set it up. - as a further question, is there any way to see what is going on when the upload is underway? I can tell it is progressing either by keeping Activity Monitor open, showing the data sent activity, and to some extent I can see if the number of tracks with cloud symbols next to them is increasing. But it is not the same as when ripping a CD to iTunes, where it displays the status of the process as the CD is copied. The information is surely available but perhaps not via one of the normal iTunes menu options?
