It has been calculated that to obtain a continuous quality music track 20 sufficiently to separate bits of information signal 48 at a frequency of 000 reports per second. Thus, a five-minute song, as such, will occupy about 36 MB. This, of course, a lot and not everyone needs music in that capacity, it's not at all a subtle hearing.
