Let the non-conscious handle the replay. The chime, if you pick it up consciously you may choose to do it consciously. I would. If I'm not following along because I'm listening down the middle and the conscious mind is apt to miss that. I just trust it happens non-consciously.

I find Paraliminals work best when I look at the booklet before I start a listening session. Consider my listening purpose and think about the questions that are written in the booklet. Think of my purpose as I set it to play and then listen along, Paul usually asks the similar questions during the intro. Then I just let it go. When I think too much about doing it right while listening I can guarantee myself not getting as much out of it as I do when I just let go and trust my mind can guide me towards my goal.
