I don't think the music really makes people spend. It can, as in the case of FloraG, drive people out if it is too extreme, which is probably why the Muzak is like that.

Part of the reason that Muzak is used in public places is because it covers up distracting background noises. Another part of the reason is that music tends to make an impersonal and foreign environment seem comforting and familar.

Some places, particularly certain types of shopping mall, try to create a more upbeat "fun" atmosphere. This is because a lot of the people are bored out of their minds, be cause the are there with a shopaholic.

If you feel manipulated because stores use music, lighting, displays, etc to make their establishments more appealing to shoppers and their consorts, sorry. For myself, I am
thankful when there is a comfortable waiting area near the ladies dressing room, and the music is loud enough that I can understand the lyrics. From my experience, you can be there for a very long time.
