The more I listen to your clip, the more I like it. Today, while browsing the forum, I launched it and set 'Replay' in my Winamp. One hour later I realized it had been going on in the background all the time. I felt very calm somehow. Much like after meditation.
I highly recommend you to check out Pat Metheny's acoustic album called 'One Quiet Night'. It has the same calm and silent mood as your clip. There are some tracks on the CD that always make me feel relaxed, no matter what I was doing before listening to them.
