Jonathan Berger, Professor of Music at Stanford University, California has theorised that young people are getting used to the sound of MP3s to the point where they are beginning to prefer the sound . For the past eight years his students have taken part in an experiment in which they listen to songs in a variety of different forms, including MP3s. “I found not only that MP3s were not thought of as low quality, but over time there was a rise in preference for MP3s,” Professor Berger said.
