Works well  mostly. I got a new lg g4 and my car's Bluetooth audio would autoplay the default media player  even taking over for the currently playing media player. It made it almost unusable. This app seems too have mostly fixed the problem. However  for some reason Amazon mp3 doesn't show up in the list of apps. This app still seems to prevent the default media player from taking over  so I'll take it.
