Luis Fonsi and Daddy Yankee's "Despacito," featuring Justin Bieber, tops the Billboard Hot 100 chart (dated July 1) for a sixth week. Bieber, meanwhile, becomes the first act with the top three best-selling digital downloads in a single week.

"Despacito" (released on Universal Music Latino / Raymond Braun / SchoolBoy / Def Jam / UMLE / Republic Records) leads the Digital Song Sales chart for a sixth week, with 140,000 downloads sold (down 1 percent) in the week ending June 15, according to Nielsen Music; the remix with Bieber accounts for 80 percent of the song's sales for a third consecutive week. The track tops the Streaming Songs chart for a sixth week, with 69.4 million U.S. streams (up 2 percent) in the week ending June 15. On Radio Songs, "Despacito" darts 6-3 with 125 million in all-format airplay audience (up 12 percent) in the week ending June 18, adding the Hot 100's top Airplay Gainer award for a fifth consecutive week.

"Despacito" also tops the Hot Latin Songs chart for a landmark 20th week (becoming the eighth title to reach the milestone, dating to the list's 1986 launch) and the Songs of the Summer chart for a third week (since the survey's return two weeks ago).

DJ Khaled's "I'm the One," featuring Bieber, Quavo, Chance the Rapper and Lil Wayne, rises 3-2 on the Hot 100; it spent five weeks at No. 3 after debuting atop the May 20-dated chart. "One" adds a seventh week at No. 1 on Hot Rap Songs and a second week atop Hot R&B/Hip-Hop Songs (2-1) and holds at No. 2 on Digital Song Sales (77,000, up 9 percent).

Bruno Mars' "That's What I Like" drops 2-3 on the Hot 100, following six weeks at No. 2 after it topped the May 13-dated chart. Still, it paces Radio Songs for a seventh week, with 154 million in audience (down 7 percent), tying his longest command as a lead artist with "Just the Way You Are" (2010) and "Locked Out of Heaven" (2013); he's led longer only as featured on Mark Ronson's "Uptown Funk!" (12 weeks, 2015). "Like" also leads Hot R&B Songs for an 18th week.

Ed Sheeran's former 12-week Hot 100 No. 1 "Shape of You" keeps at No. 4 and extends its record for the most weeks spent in the top five from a song's debut, having now tallied its first 23 weeks on the Hot 100 in the top five, dating to its start at No. 1 (Jan. 28).

Rounding out the Hot 100's top five, Kendrick Lamar's "Humble.," which topped the May 6-dated Hot 100, is steady at No. 5.

Future's No. 5-peaking "Mask Off" remains at No. 6 on the Hot 100 and The Chainsmokers and Coldplay's No. 3-peaking "Something Just Like This" lifts 8-7, as The Chainsmokers spend a 59th consecutive week in the Hot 100's top 10, a streak second only to Katy Perry's record 69-week run in 2010-11. The track logs a 12th week atop the Hot Dance/Electronic Songs chart.

Zedd and Alessia Cara's "Stay" rebounds 9-8 on the Hot 100 after climbing to No. 7; Post Malone's first Hot 100 top 10, "Congratulations," featuring Quavo, rises to a new best rank (10-9); and Lil Uzi Vert's "XO TOUR Llif3" descends to No. 10 from its No. 7 high.
