I don't understand what you want to do here.
I'll try to explain again:
So, let's say I'm playing a track from playlist A Now, I would like to start playing a random track from playlist BTo do this, I would have to
Click on playlist B Select a random track manually from playlist B (or ctrl+h and then select a track) Double click on the track to start playing itThe play button controls the currently playing track (from playlist A, in my example) So, pressing play just plays/pauses the current playing trackWhy can't you just press play?
Solution
A button that shuffles the current selected playlist (not the one that is currently playing) and then plays a track from it.Behavior when using this modified feature
I am playing a track from playlist A I press play/pause button: the current track plays/pauses I click on playlist B There is a "Shuffle Play" button between the "Clear Playlist" and "Undo" buttons. I click on "Shuffle Play" The playlist B is shuffled and a random track from the playlist B starts playingHope this makes it clear. I'm pretty sure many people would like to have such a feature, it is pretty convenient this way.
