I diagree with ojgalli as to the reasoning.
He is doing an immediate and sudden comparison. relying on attempting to remember a snippet of sound. My (and others) rely on long passages, and NOT so much on memory of the actual sound, but on how the sound made you feel. That feeling is easy to remember. And if it is repeated, the collected feelings of each product with the different music can give one a clear preference, which will last when actually owning the product.
One will remember some of the highlights of the sound, but the meat of the comparison is the emotional response.
