99% of the userbase doesn't even know what Hi-Fi music is, so doubt adoption will be a thing. Look towards apple music, deezer, tidal, etc for hi-fi music.
Honestly hifi isnt practically useful. It's extremely difficult to tell the difference between flac and 320kps mp3 (very high quality setting in Spotify). Most people can't tell the difference even with audio equipment costing a fortune.
I used to be obsessed with getting the very best quality but frankly I gave up because there just is no discernable increase in fidelity (I use a dac+Sennheiser hd 600)
