Hiding All Apple Music Features in iTunes (Apple Music Menus, Radio, Connect & Heart Column)
If you go into Preferences &gt; General there's two things that you need to uncheck to disable Apple Music.


Show Apple Music
iCloud Music Library


For the Connect Menu, you can do this by going into Preferences &gt; Parental and checking the Apple Music Connect tickbox.

Now I'm not entirely sure what ticking the Internet Radio box does in Preferences &gt; Parental but it doesn't seem to hide the Apple Music Internet Radio button. I currently haven't found a way to hide this radio button.

Edit: Hiding the heart column in iTunes is simple enough. Just right click the heart column in iTunes and scroll down till you see the Love option that's ticked.
