Where are my Apple Music playlists stored?

Please make the new windows Apple Music and TV apps have a way to export and import the playlists. I really don't want to have to create the same playlists on my 5 computers and 5 devices.

OR better yet, MAKE THEM SYNC IN THE CLOUD.

What a novel idea.

For crying out loud I have logged into each of the apps on all my devices, why can't you use my account to send the playlists from one to all the others?
