Why does background music on iOS stop when launching a monogame app?

iOS

I have a game which stops already-playing music in Spotify. I have tracked it to the base Game constructor causing this to happen. Anyone know why, or how to keep background music playing?

Seems to be a known bug since beginning of 2013:

I resolved it using response from Andreyul from https://github.com/mono/MonoGame/issues/735

Game developer can call
AVAudioSession.SharedInstance().SetCategory(AVAudioSessionCategory.Ambient);
in UIApplicationDelegate.FinishedLaunching().

SoloAmbient is the default.
