Explanation:
Music is used in TV commercials because a song is more likely to get "stuck" in your head than just someone talking about a product. Then, when you see that product online or in a store, you will have a higher chance of buying it if you have a connection with it (remembering the song). It is a marketing technique.

Jingles get stuck in your head so you are more likely to think about the product.
