But it increasingly looks like it won't be a one-off.
Another Latin American song, Mi Gente, has replaced Despacito at the top of Spotify's Global Top 50. Here in the UK, it's just broken into the top 20.
"It's amazing. It's such a blessing," says singer J Balvin, the Colombian artist who's behind the song.
Already a huge star in South America, Balvin has been credited with revitalising reggaeton - a hip-hop-infused blend of reggae and rap that originated in Puerto Rico in the late 1990s.
