On the Queue tab, I go to ‘Save’ a song to an existing playlist by clicking the floppy disk icon. The UI pop-up shows “Add to Playlist” and I choose one of my existing playlists. I assume this means that I will append the track to the selected playlist. However, this causes an over-write of the existing playlist and all the original songs are gone!
Is this correct behaviour? If so, how do I append tracks to an existing playlist?
