Music is used in ads for multiple reasons. One reason is that the makers of the product or service want you to associate a certain song (say, a popular one) with their product, or they might want you to associate the feelings (such as happiness, positivity, nostalgia) that the song invokes with what they are selling and hope that you will buy the product or service based on how the song makes you feel.

Mad ads are commercials that are designed to get your attention. Often the meaning behind the ad is to get something stuck in the brain of the consumer. A song, or a slogan for example. The belief is, if you are thinking about the ad, you will buy the product.
ads boost up the sales of a product as they show the importance or what the product can do or what benefits these products give.
There is no real "hidden message" in the Apple song (if one is referring to the Apple, Inc. theme song). However, Apple songs (ads) have hidden meanings in them such as a hint towards a new product.
