I really hate that I am unable to sync my Apple Music Subscription music without also syncing my Music on my mac which I want to sync manually via a cable to my iPhone. I feel like I am getting ripped off as I can barely use the functionality of Apple Music which I am paying for. The two services should be separated.
I do not want Apple to sync my music on my Mac to the cloud, I have over 62,000 songs most of which are not available from Apple Music and if they are I have customized all the metadata to be just how I want it, and I don’t want to take the chance that Apple will mess with it. I tried iTunes Sync when it first came out, and it messed up my whole library and took me years to get it back to exactly how I wanted it.
I want to be able to save playlists from Apple Music and have what I do in Apple music be consistent across my devices, but should not have to also do the same with my personal music library. I don’t want my music to be recompressed (bad enough to have to do use Apple Uncompressed instead of the more ubiquitous Ogg) or messed with in any way. Bad enough that I have to use the awful Finder Sync for music, that can’t be force quit.
Honestly I wish Apple Music and Music were split as two apps, and your mac music could become part of Apple Music if you wanted it to, but it should be your choice.
