FRENCH MONTANA

In April, French Montana posted a video on Instagram of him holding a white cup and hopping slackly to his own music, adding the hashtag #Unforgettabledancechallenge. Within a week, the video for his single “Unforgettable” — which featured a Ugandan dance troupe doing the same dance — racked up 10 million views, further popularizing the hashtag, with a bevy of stars (Drake, Diddy, DJ Khaled) partaking in the challenge. By August, the song’s methodical viral campaign scored Montana his first No. 1 on the Hot Rap Songs chart.
