You can download music from the store to your computer; however, even though it stores in iCloud, it will not show up on your phone to download unless you subscribe to Apple Music and pay the fee. Until recently, my purchased music on my computer was available to add to my phone. Now if I look for it in search, it’s not there, but I can buy it again for my phone. I do have iCloud shared across devices, but iCloud isn’t in the menu on my new phone unless I subscribe to Apple Music. Every site I’ve searched on this problem provides me with the solution to install Apple Music. So my reality is that iCloud sharing is no longer allowed. Thanks Apple, cuz you obviously don’t make enough on the equipment, through iTunes etc.
