I am a subscriber to Hearing Things, so I knew the context going in. But I thought the second sentence made it clear they were music journalists and not artists.

Hearing Things publishes playlists as music reviews—text, that is. And the playlists are available on all music streaming platforms.

But this blog announced that their playlists will no longer be on Spotify due to Spotify's continuing enshitification—I found no reductive moralism, only an interesting bad review.
