Sticky melodies

Why is it that I oftentimes immediately forget the name of someone who has just introduced themselves to me, but not for love or money get a commercial jingle out of my head?

A recent Q&A on the New York Times website points to the success of “earworms.” It’s “music characterized by simplicity, repetitiveness and incongruity with listeners’ expectations is most likely to become ‘stuck.’ ”

Good news for advertisers I would think!
