On desktop version of Spotify, and older versions of the iOS app, one could hit the + button on a song to save it to their library. On iOS, this + button changed to a heart icon. So now, if you are using the newer iOS version, if you heart a song it also adds it to your library. Why is this different? How can one add a song to their library using the + without leaving hearts all over the place? Please see below showing the unnecessary, confusing redundancy.
