                     * 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".
