I found all of these rather insipid and irritating in use. Since I do often use background music, I can only say these are weak.

Well, certainly everyone has thier perspective on what constitutes good music. In this case the music is designed to be in the background and non confrontational. It might have been more constructive had you gleaned what exactly was not working for you rather than sweeping generalizations. It appears from other reviews most have truly enjoyed them and allowed the music to be what it is, "ambient".
