After a record-tying 16 weeks at the top of the charts, "Despacito" has officially been dethroned, losing its No. 1 spot on the Billboard Hot 100 to Taylor Swift's latest karma-ignorant single, "Look What You Made Me Do".
Look What You Made Me Do also posted the year's most downloads, at 353,000, the most since Justin Timberlake's feel-good summer song Can't Stop The Feeling! in May 2016.
As Billboard notes, the song has jumped from No. 77 on the Billboard Hot 100, where it initially debuted based on a few days of airplay, to No. 1. Despacito's lifetime combined sales to date stand at 1.8m.
In third place was DJ Khaled's Wild Thoughts, which features Rihanna and Bryson Tiller and samples the 1999 Carlos Santana hit Maria Maria.
Despacito is the most streamed song of all time.
Jonas Blue is the highest ranking British artist on the list - Mama ft. Liam Payne's hit Strip That Down followed with 541,000 sales.
It was the biggest song of the summer after being number one for an impressive 11 weeks. The track was originally released in 2015 but reached a new peak on the Official Singles Chart at No.2 in June in the wake of the terrorist attack on Manchester Arena. Proceeds from the reissued track went to the We Love Manchester Emergency Fund in coordination with the British Red Cross.
