Berger then said that he tests his incoming students each year in a similar way. He has them listen to a variety of recordings which use different formats from MP3 to ones of much higher quality. He described the results with some disappointment and frustration, as a music lover might, that each year the preference for music in MP3 format rises. In other words, students prefer the quality of that kind of sound over the sound of music of much higher quality. He said that they seemed to prefer “sizzle sounds” that MP3s bring to music.
