Sigh, yeah, that's actually a great point. Wonder how many great pairs of ears have been ruined by opening a random youtube tab while Spotify is playing with the quiet normalization mode enabled.
And just like the PS4 example, it's just insane to me that Spotify Connect doesn't mandate normalization.
What annoys me is they're mixing together two features (namely normalization and dynamic range compression) and putting them behind one toggle.
I want normalization, it's hugely annoying playing music on my PS4 because the Spotify client doesn't have it there and I constantly have tot tweak the volume.
I do not want compression.
But on my phone and computer I have to use their 'normal' normalization level and take the compression because 'quiet' means I am constantly turning up my sound level when listening to Spotify and turning it back down when I do anything else so my ears don't get blasted.
