The reason guns kill people is because of a spring mechanism in guns, causing the hammer to fall, causing the primer to ignite, causing the projectile to ....
The reason most music sounds like shit is because the sound engineers...
must obey the artist they are recording
FTFY
Though there are sound engineer unions, there has never been any movement within these groups to ruin music with dynamic nor bit compression. The trend of national music, known as the Loudness Wars, made possible by audio technology (not necessarily new or cutting edge, either) and those that competantly operate it and engineer audio, but only at the command of producers and artists.
IOW please stop blaming audio engineers, because its the same thing as blaming gun violence on springs
Once upon a time for a few decades, engineers perfected tracked and reproduced audio, perfected in the sense that, with intention and understanding of the underlying processes, the national product always had certain aural qualities such as separation and dynamism that worked with the artistic piece itself effectively making the audio reproduction science into a subtle or not so subtle artistic instrument that could be reasonably reproduced even on really crummy components.
Then artists got rich and decided they knew more about audio engineering than audio engineers.
There are some artists, of course, that took the time to actually learn engineering audio, just like there are writer-director-producer-actors in the film industry. But most recording artists have their one strong suit, and its in performance, composition, poetry and music, and not in visualizing the shape of the sound of how one instrument's single note at that particular time index pokes through the layered and spectrum overwhelming frequencies the other instrument happens to be filling. The artist with their technically untrained ear just says "yeah, but I can't hear the bass" or "you gotta turn my guitar up and my vocals down."
So please don't thank President Obama sarcastically and don't blame photographers for gimpy runway fashion models and what they're wearing... it was some artists with control-issues and a distinct lack of critical ear , and a commercial trend, that ruined recorded music; it certainly was not professional audio engineers.
