The mainstream arrival of a new 17-year-old pop star reached its final stage this week as Billie Eilish\u2019s first album put up big numbers and debuted at No. 1 on the Billboard chart. \u201cWhen We All Fall Asleep, Where Do We Go?\u201d (Darkroom/Interscope), which was written and produced entirely by Eilish and her 21-year-old brother, Finneas, earned a total of 313,000 album equivalent units, including a robust 170,000 in sales and 194 million streams in its first week, according to Nielsen. Those numbers gave Eilish the second-largest sales week of the year so far, behind only Ariana Grande, whose \u201cThank U, Next\u201d debuted with 360,000 units in February. Eilish\u2019s album succeeded across formats: Its streaming total was the third-highest ever for a female artist (behind Grande and Cardi B), while the LP also sold 15,000 copies on vinyl, Billboard reported, the best sales week in that format this year.

Interest in his music surged amid the outpouring of grief in the wake of his death, leading \u201cVictory Lap,\u201d his major-label debut from last year, to its biggest week yet. \u201cVictory Lap\u201d (Atlantic) debuted at No. 4 in March 2018, but surpassed those totals following his slaying, with 62 million streams and 17,000 in sales for a total of 66,000 units. Grande\u2019s \u201cThank U, Next\u201d (Republic) is No. 3 in its eighth week on the chart, owing largely to another 63 million streams, while George Strait\u2019s \u201cHonky Tonk Time Machine\u201d is No. 4, with 44,000 in sales and 7 million streams. \u201cDeath Race for Love,\u201d by the emo rapper Juice WRLD, is No. 5.
