Background music has a huge effect believe it or not...
This question is for a man of psychology. There is nothing more powerful in selling things than sex appeal. This is why you see in advertisements for cars to careers women selling it. Additional research has also established that the most used word in the U.S. marketing is "On Sale" or so much off. Third most powerful is appeal to a person's patriotic feelings. Stores clad themselves in red white and blue.
Background music like Susan said (her name is spelled Susana in Afghan) is also powerful in making people linger around in a store and the longer they stay the more they spend. Psychologists have found that music must be without words for it to be effective, otherwise people get lost in the words and distracted from buying.
