                 * This is so horrible that I can't find other words to describe how bad the BackgroundAudioPlayer
                 * is in Windows Phone!
                 *
                 * First of all the events are fired totally differently between Windows Phone 7 and Windows Phone 8.
                 * Secondly the events related to when tracks end arae totally wrong and horrible! Let me explain:
                 * - We get here the PlayState.Stopped event when the track ends.
                 * - We get the event here BEFORE the AudioAgent gets any events.
                 * - AudioAgent correctly gets the PlayState.TrackEnded event, but it gets it after we have received the
                 *   event here.
                 * - We NEVER get the the PlayState.TrackEnded event here.
                 * - Which is not the case for Windows Phone 7, because it first fires PlayState.TrackEnded.
                 *
                 * So this code here is a horrible kludge that just guesses that Windows Phone means "track did end"
                 * when the state is stopped and the play position is still 0.
                 *
                 * Johan, when you return from the future to this piece of code, don't even try to change it or "fix it".
