As a person who works in marketing, I understand the value in creating something catchy that will allow your brand, product or service to take off.  Being top of mind is essential, and something all most marketing professionals strive for.

However, jingles are an aspect of advertising that I have never quite understood.  Yes, most of them stick in your head, which I guess is one way to force people to remember you.  But most of the time, I am so irritated by jingles that it almost forces me to hold it against the company that is putting them on.

Do people actually respond to jingles anymore?  Do they negate the credibility your company may have previously received?  Or are they stuck in your head so long you are forced to follow through with their request and become a customer?
