The track, from the 13 Reasons Why, Season 2 soundtrack, which rises 34-29 on the Billboard 200, is Gomez's 20th top 40 Hot 100 hit and her 15th in a row, as all 15 songs that she has sent to the chart beginning with "Love You Like a Love Song" in 2011 have hit the top 40. In that span, she has charted her first seven top 10s, led by the No. 5 hits "Good for You," featuring A$AP Rocky, and "Same Old Love," in 2015-16.
In that stretch, Gomez's streak of 15 consecutive top 40 Hot 100 hits is the longest active run of any artist.
"Back" lifts 49-29 on the Digital Song Sales chart (12,000 sold, up 20 percent, in the tracking week, according to Nielsen Music); 48-45 on Radio Songs (25.2 million in airplay audience, up 21 percent); and 50-49 on Streaming Songs (10.9 million U.S. streams, up 5 percent).
The song should surge further following the June 5 arrival of its proper official video.
As previously reported, Drake's "Nice for What" rules the Hot 100 for a sixth total week; Lil Baby and Drake take over atop the Streaming Songs chart with "Yes Indeed," which holds at its No. 6 Hot 100 high; Cardi B, Bad Bunny and J Balvin return to the Hot 100's top 10 with "I Like It," at a new No. 7 peak, following the premiere of its official video; Drake's "I'm Upset" launches at No. 19; and, Pusha T debuts four songs on the survey.
In even more Hot 100 chart moves:
Dan + Shay previously reached a No. 42 Hot 100 high with its breakthrough single "19 You + Me" in 2014.
"Dinero," Jennifer Lopez feat. DJ Khaled & Cardi B
After the May 24 premiere of the official for the song, which Lopez and DJ Khaled performed on the Billboard Music Awards May 20, it enters the Hot 100 at No. 80, up 69 percent to 6.9 million U.S. streams in the week ending May 31.
Lopez makes her first Hot 100 visit since July 2016, when her charity single with Lin-Manuel Miranda, "Love Make the World Go Round," charted for a week at No. 72.
As for more Cardi B …
"Girls Like You," Maroon 5 feat. Cardi B
The song, originally available on Maroon 5's 2017 album Red Pill Blues by the band solo and released May 30 as a single featuring Cardi B, enters the Hot 100 at No. 94, powered by its No. 12 start on Digital Song Sales (19,000). Its star-studded video (here is a rundown of all the women in the clip), also released May 30, further sparks the song's 2,212 percent blast to 3.9 million U.S. streams.
