Add to library still exists. So you can add to library without favoriting it. It’s just that the add to library button is not there in the main screen. Which I agree will be annoying for anyone who only wants to add to library.

I don’t get it. Hit the star to add to library.

This is what I have been waiting for AM to implement. One button to add to library and “love” it.

The previous system was what kept wanting me to go back to Spotify.

This is definitely a very good change.
