I really like this song but I guess given the “loudness wars”, music producers tend to deliberately add (white/pink) noise at quiet passages of the songs in order to trick streaming/loudness algorithms. And this is unacceptable for my (OCD) ears when I listen to this kind of (artificial) artifacts. You just can’t unhear them. 
It happens a few times during the song below. First occurrence is from 18" to 35" when there’s just a piano + vocal passage.
