Long ago (ca 1985) I was working on a film for Sting.  I had him in the
studio to fix a couple things, one of which was tape hiss on a Space Echoed
guitar track,  He told me, "Leave it in, it reassures people."  That has
since turned out to be quite a prescient observation.  Among other things
telephone companies have done a lot of work with adding noise in digital
paths, for the very same reason,
