I often listen to music when I'm driving. And when driving, I like to listen to new playlists. At the moment there's no simple way to add current song to a playlist. Could there be some kind of gesture or a button short cut to add song to starred or whatever?
This idea was submitted more than one year ago but, unfortunately, hasn’t gained enough kudos during that time (50 kudos/year). To keep an overview of the active ideas in this forum, this idea will be closed for now. Note that this does not mean the idea has been declined by Spotify.
Please feel free to re-post this idea if you still feel you want this implemented. With a little change in presentation, maybe next time it will gain the necessary support from the community.
