This event is called whenever the SDBPlayer.Pause function is called.
The Pause function is a toggle. If a track was playing, the track will now be paused; if the track was paused, the track will have resumed playback. Therefore, if the current playback state is important, you should check the state of SDBPlayer.isPaused (and maybe also SDBPlayer.isPlaying) on receipt of this event.
(TBD: what happens if Pause is called while playback is stopped?)
