* 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".
