In September 2019, at the encouragement of friend and colleague Joe Levy, Christgau began publishing the newsletter "And It Don't Stop" on the newsletter-subscription platform Substack. Charging subscribers $5 per month, it has included his monthly "Consumer Guide" column, podcasts, and free weekly content like book reviews. Christgau was skeptical of the platform at first: "Basically I told Joe that if I didn’t have enough subscribers to pay what I made at Noisey by Christmas I was going to quit. I wasn’t going to do it for less than that money. I had that many subscribers inside of three days." By May 2020, "And It Don't Stop" had more than 1,000 subscribers. Christgau was ambivalent about the platform at first, but has since found it "immensely gratifying", explaining that, "A man my age, who is still really intellectually active? It is tremendously flattering and gratifying that there are people who are ready to help support me."
