The annual warm-weather ranking splashes back onto Billboard's charts menu, as the race officially begins for the top summer song of 2017.

What will be the top song of the summer? We can officially begin making our way toward the answer, as Billboard's annual Songs of the Summer chart returns to Billboard.com.

The 20-position Songs of the Summer running tally tracks the most popular titles based on cumulative performance on the weekly Billboard Hot 100 chart from Memorial Day through Labor Day. At the end of the season, the top song of the summer will be crowned.

First, a few flashbacks: Drake's dancehall-tinged "One Dance," featuring WizKid and Kyla, reigned as the top song of the summer of 2016. OMI's reggae/pop hit "Cheerleader" won top honors for 2015, while, the year before, Iggy Azalea's debut smash "Fancy," aided by Charli XCX's vocal hook, ruled as the top song of the summer of 2014. The previous official songs of the summer this decade: Robin Thicke's "Blurred Lines," featuring T.I. and Pharrell Williams (2013); Carly Rae Jepsen's "Call Me Maybe" (2012); LMFAO's "Party Rock Anthem," featuring Lauren Bennett and GoonRock (2011); and, fittingly, Katy Perry's beach-centric "California Gurls," featuring Snoop Dogg (2010).

This year, Luis Fonsi and Daddy Yankee's "Despacito," featuring Justin Bieber, the Hot 100's current leader, ranks at No. 1 on the first Songs of the Summer survey (dated June 17), followed by Bruno Mars' "That's What I Like" at No. 2 and DJ Khaled's "I'm the One," featuring Bieber, Quavo, Chance the Rapper and Lil Wayne at No. 3. Rounding out the first Songs of the Summer chart's top five are Kendrick Lamar's "Humble." (No. 4) and Ed Sheeran's "Shape of You" (No. 5).

Who'll win this summer's chart battle? We've got a hot 100 days, give or take, to find out.
