when the last song of a playlist finished playing, but playlist is not in repeating mode. hitting play from bluetooth connected car radio system or pc doesn't do anything. take out the phone and press play would play the last song of the list.

1. ideally, I would expect hitting play from bluetooth connected car radio system or pc would play from the beginning of the playlist

2. is it possible to set playback mode globally, not on per playlist setting? I haven't found an easy way to add a new music file to existing playlist (generated from play by location). whenever I add/delete a couple songs/directories on my phone, I just delete existing playlist and create a new one from play by location. would be good to be able to achieve the same thing with some sort of update command, so new songs are added in the proper proper order by their directory and their name within their directory while songs with files deleted are removed from the playlist
