The track led the weekly Songs of the Summer chart each week from start to finish.

In a race that it dominated from beginning to end, Luis Fonsi and Daddy Yankee's "Despacito," featuring Justin Bieber, is Billboard's No. 1 song of the summer of 2017.

The collab crowns Billboard's annual Songs of the Summer chart, which tracks the most popular hits based on cumulative performance on the weekly Billboard Hot 100 chart from Memorial Day through Labor Day.

"Despacito" led Songs of the Summer for all 14 of the survey's weeks this year. It's the fourth song this decade to run the table, following last year's champ, Drake's "One Dance," featuring WizKid and Kyla; Iggy Azalea's "Fancy," featuring Charli XCX, in 2014; and Katy Perry's "California Gurls," featuring Snoop Dogg, in 2010.

"Despacito" is the first Songs of the Summer season-ending No. 1 for Fonsi, Daddy Yankee and Bieber (none of whom had previously ranked in the top 10 on any annual Songs of the Summer survey). It's also the first predominantly Spanish-language Songs of the Summer winner since Los Del Rio's "Macarena (Bayside Boys Mix)," which took top honors for 1996. The only other No. 1 summer song not sung (primarily or at all) in English: the very first, Domenico Modugno's Italian-language "Nel Blu Dipinto Di Blu (Volaré)," the leading title of summer 1958, the year that the Hot 100 began (that Aug. 4).

"Despacito" first hit No. 1 on the Hot 100 dated May 27. The Songs of the Summer running tally covered the weeks dated June 17 through Sept. 16 this year; on June 17, "Dance" was in its fourth of its record-tying 16 weeks at No. 1 on the Hot 100 (to date), and the song topped the Hot 100 until this week, as Taylor Swift's "Look What You Made Me Do" soars to No. 1 and "Despacito" dips to No. 2 (on the Sept. 16-dated chart). ("Despacito" remains tied for the most weeks spent atop the Hot 100 with Mariah Carey and Boyz II Men's 1995-96 smash "One Sweet Day.")

Bruno Mars' "That's What I Like" is the No. 2 song of the summer. The track topped the May 13 Hot 100 (before the Songs of the Summer tracking span began) and spent almost the entirety of the seasonal chart's tracking period in the top 10 (through the Sept. 9-dated list).

DJ Khaled boasts the Nos. 3 and 4 songs of the summer of 2017, respectively: "I'm the One," featuring Bieber, Quavo, Chance the Rapper and Lil Wayne, and "Wild Thoughts," featuring Rihanna and Bryson Tiller.

Ed Sheeran's "Shape of You" wraps as the No. 5 song of the summer, having set the all-time record for the most weeks spent in the Hot 100's top 10 (33).
