Using the WMPLib

I get al list of song from my music folder and set them in a playlist and programatically play. The song is playing whilst I am doing other things with the application.

I am wondering why it stops, and how to alter this.

What I have tried:

WindowsMediaPlayer w = new WindowsMediaPlayer();
         WMPLib.IWMPPlaylist pl = w.newPlaylist("newL", "");
         //throw new NotImplementedException();
         foreach (string m in musicF )
         {
             //playFile(m);
             // w.newMedia(m);
             pl.appendItem(w.newMedia(m));
             //w.controls.stop();
         }
         w.currentPlaylist = pl;
         w.controls.play();
