i havent looked at this function for a couple of years and its in bad shape! Infact i've been spending the past couple of nights looking at this and still havent got it working correctly, so its time to cut my losses with this. Given you are the first person to raise this all this time i guess its one of the undiscovered features of MB that no one knows about and no one will miss, so i will leave it for now - it will still require clicking to activate and should work better if you dont shuffle the playlist but still has a few quirks
