The country singer Morgan Wallen holds at No. 1 on the Billboard album chart for a second time with his streaming hit “Dangerous: The Double Album,” topping a slow week for music sales.

“Dangerous,” which has 30 songs, notched the equivalent of 159,000 sales in the United States, down 40 percent from its opening, according to MRC Data, the tracking service formerly known as Nielsen Music. The album’s total includes 177 million streams and 22,000 copies sold as a full package. Even with those reduced numbers, “Dangerous” had by far more streams in a week than any country album has had before.

“Shoot for the Stars Aim for the Moon” by the New York rapper Pop Smoke, who died last February at age 20, is in second place, continuing its remarkable chart run. In the 29 weeks since the album came out in July, it has stayed in the Top 10 for every week but one, when it dipped to No. 11 at the end of last year; for much of that time, it has stayed comfortably in the Top 5.

Why Don’t We, a boy band, opened at No. 3 with “The Good Times and the Bad Ones,” with the equivalent of 46,000 sales. Taylor Swift’s “Evermore” is No. 4 in its sixth week out, and Ariana Grande’s “Positions” is No. 5.

Last week’s top single, Olivia Rodrigo’s smash “Drivers License,” holds at No. 1 on Billboard’s Hot 100 chart.
