One of the suggested resolutions was to use the audio_service package in order to obtain a foreground service, which Anytime does use.

When you pause an episode it does make Anytime eligible for killing. I think this is fine, but what Anytime needs to do is be better at recovering. Often it will show the episode that was playing before being killed, but not always.
