Kinda shocked that Apple hasn't added this yet, especially with how hard they're pushing Apple Music these days. As of now, we're forced to use Apple's "Remote" app to access and control iTunes on Macs. However, Apple Music features still aren't supported with this method - you can't play Beats 1, can't browse Apple Music, etc. I thought maybe the macOS Sierra update would finally remedy this, but I guess not. Too bad. Spotify Connect is the main reason that I use Spotify, and would love to ultimately ditch it and solely use Apple Music.
