What is TAKE AUDIO FOCUS? I never heard before

[rabaimorp]

Its an app operation that is allowed for all apps by default, however the user can disable it manually. It allows apps to play audio that takes over (stops) other audio playing at that time. All apps do this by default, but I usually disable this in the apps I use because it prevents multiple apps playing audio at the same time. The bug is that SimpMusic simply stops playing audio entirely if I disable TAKE_AUDIO_FOCUS for SimpMusic by running the command as root or adb shown above.
