Audio Soft

I am running windows 8.1 preview on a Lumia Icon. When I write email if I close my music player (any music player not any one specifically) the music will still be playing but the app is not visible when I hold the back key to get the running apps. It is obviously running, why isn't it visible? I have to re-launch the app to be able to access it to change the song or to close the app.
