the sound of listening

As per the "Artist Intent" rule (https://musicbrainz.org/doc/Style/Principle/Error_correction_and_artist_intent), the release group and releases should be spelled in lowercase.
Proof of the intent can be found on https://markguiliana.bandcamp.com/album/the-sound-of-listening -- see 2nd paragraph below track list:
"In complete contrast to his latest BEAT MUSIC! work, ‘the sound of listening’ (intentionally lower case) is a deeply honest and expressive album by a musician who knows where he’s headed and what he wants to say with people he deeply trusts."
