Electronic music is unique in its high degree of contrast compared to older methods of creating music. Modern digital production done well can also create high degrees of contrast even for music that is not purely electronic, though to some degree that would turn it into electronic music (almost all modern popular music has purely electronic components/layers, so calling electronic music a separate genre will soon stop making sense). However, purely electronic music on average will have the highest degrees of contrast due to the fact that such contrast is baked into the tools of production.
One type of music is not superior to another, but no one can argue that a high contrast, purely electronic song is unlike any other type of music that came before, and this is exciting because it remains a very new set of artistic tools in the tens of thousands of years old history of music.
Just like our brains are adapted to be sensitive to visual contrast, the same is true of auditory contrast. I realize this is not the classic way to describe auditory terminology, but the effect is identical; just like when processing or creating images there is an artistic choice made if increasing contrast is the desired effect. Having good speakers makes it immediately clear which songs are produced with good separation of tones and instruments and loudness and which are not.
The enormous caveat to all of this is that how we listen to music is fundamentally changing how it is created. Because almost all music we listen to is now a recording (digitalized), even when live at a concert you are hearing it through speakers (unless a very small venue), this warps our perception of what music has the most contrast. If you stand next to a violin it is obvious that there are dramatic and engaging variations in its sound, but listening to that same violin on a variety of different speakers will make this impossible to recreate. So the corollary is to teach your children to create music. It will be some of the best you’ve ever heard.
