Please highlight the “favourite” attribute of a song while it’s playing.
I’d use more the “add to favourites” feature but … I find myself clicking on it whenever I listen to a song I’d like to set as favourite (again and again and again …) because the heart shaped icon/link doesn’t change its appearance, hence I don’t know if I already added that specific song to favourites or not.
A “favourite” status icon during the playback would be helpfull. Even making the heart icon switch (maybe: empty vs full coloured heart) accordingly would be enough
