Just FYI, mobileLockIdleTimer will prevent the device locking and
turning off the screen, which is a real battery killer. A mobile device
can play audio with the screen off for many, many hours. Of course if
you actually need the screen on, no problem.

On iOS, assuming you have the audio background mode set (in the
info.plist), the device doesn't suspend your app while it's still
playing audio. It may be the case that the way LiveCode works with audio
APIs, or the way you're using them, means you stop playing between
tracks for too long, so the system assumes the audio is finished. Might
be worth further investigation.
