Sharing the music
Will the function “sharing your music” in AppleMusic be able in Russia?
Apple Music playlists can be shared with any Apple Music subscriber, but the tracks in the playlist have the be licensed for that region for it to work, which can sometimes limit international use of that feature.
Apple Music in Russia has the Family subscription option for sharing this subscription with a Family Sharing group.
Other sharing options for music are not supported anywhere in the world.
