I use Amazon's MP3 store from time to time to haven't disabled it, but since the latest update, earlier this year, this stupid app is auto-starting when I hook up my Bluetooth. I have looked all through the app's settings and can't find an auto-start option. Seems like there is a more global setting that determines which music app is the default for an auto-play when Bluetooth is connected, but I can't find it. Little help please?? Thanks!
