c# - Media Element will not play a song for the first time, or at all. -


i have little problem playing song selected simple listpickerflyout, now, works 

private async void musicfileslist_itemspicked(listpickerflyout sender, itemspickedeventargs args)         {             storagefile selectedmusic = sender.selecteditem storagefile;              using (irandomaccessstream stream = await selectedmusic.openasync(fileaccessmode.read))             {                 this.musicplayer.setsource(stream, selectedmusic.contenttype);                 this.musicplayer.play();             }          }

it works fine except tiny little bug disturbs me- first time select song- not play, second time. debugged , saw enters handler first time too, reason plays second time. strange, told should write event handler following way - 

  private  void musicfileslist_itemspicked(listpickerflyout sender, itemspickedeventargs args)         {             storagefile selectedmusic = sender.selecteditem storagefile;             this.musicplayer.autoplay = true;             this.musicplayer.source = new uri(selectedmusic.path);             this.musicplayer.play();         }

to me - looks fine, won't play song @ all. explain why first 1 not working properly, second 1 not working @ , proper way play music using media element ?
