"Despacito," "I'm the One" & new "2U" make Bieber the first act ever with the week's top three-selling downloads.

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.

As we do each Monday, let's run down the top 10 of the Hot 100, which blends all-genre sales, airplay and streaming data. All charts will update on Billboard.com tomorrow, June 20.

"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).

Bieber further makes history, becoming the first artist to rank at Nos. 1, 2 and 3 concurrently on Digital Song Sales, as David Guetta's "2U," featuring Bieber, launches at No. 3 on the sales tally with 72,000 first-week downloads sold (following its June 9 release), below "Despacito" and "I'm the One," respectively. "2U" debuts at No. 16 on the Hot 100, also sparked by its No. 21 arrival on Streaming Songs (14.2 million U.S. clicks) and No. 40 entrance on Radio Songs (28 million impressions).

Bieber, meanwhile, doubles his longest Hot 100 reign. Of his four prior No. 1s, he had ruled the longest with "Sorry," for three weeks in early 2016.

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.

Just beyond the Hot 100's top 10, Childish Gambino's "Redbone" reaches a new peak (16-14) and Halsey's "Now or Never" enters the top 20 (21-20). Plus, Selena Gomez's "Bad Liar" leaps 45-23, hitting a new high (passing its prior best of No. 27), as it vaults 34-12 on Digital Song Sales (34,000 sold, up 100 percent) and re-enters Streaming Songs at No. 34 (12.2 million U.S. streams, up 34 percent), following the June 14 premiere of its official video.
