We play high resolution music because we are convinced that the lack of natural analog music affects our brains and ears. If you dont feed your brain with certain frequencies from time to time it will disable the corresponding neural networks. Of even more importance we consider the quality of soundwave reproduction. The digitalization of audio in CD format, or even worse compressed formats like mp3 etc., results in omitting large parts of the natural endless-value shaped soundwave.
In a conference of audio engineers and radiomakers in 1939 it was decided to raise the general pitch of music higher for military reasons. This was often critizised and never turned back. There are numerous reasons to not stress your vegetative nerve-system with the 440hz.

And your body and spirit soul don't care about what you think you like. The more complex harmonic music like Rahmaninoff or Zappa is there to trigger long-term unused brain neurons, the more intense pieces are there to wake you up, and some of the simple songs might just touch your soul. There are no dark lyrics here to be heard.
