I believe there is a method to Roon’s madness with playlists.
If you have an album displayed, the thought is that you either want to play the whole album or a single song. Because of user requests, play from here was added by right clicking (long press) a song and clicking play from here at the top of the screen.
With playlists, the thought was you either played the playlist, or found a song as a starting point and clicked play, which plays from that point on. ie. play from here. It was thought that if you wanted to play a single song, you wouldn’t go into a playlist to find it. However, playing a single song was added as well by using the right click (or long press).
Anyway, it’s opposite and kind of confusing.
A while back, the Roon guys started a thread asking for ideas for playlists. So, they are looking at working on them in the future. You can check it out here:
