One of the bloggers I follow posted a list of songs she purchased as a result of watching commercials. I recognized all of the songs and commercials but none of them compelled me to purchase the music. These songs embedded in the linked commercials did manage to persuade me to part with a few bucks so I could hear them again. I think you can tell a lot about a person by listening to the music that hooks them.
