One of the most creative versions was recorded in the United Arab Emirates and combines the Siri beat with beatboxing and Indian classical singing.
The beatboxer in the video is Carl Frenais, the frontman of a group called Carl & The Reda Mafia. The video was supposedly intended to be private and only shared amongst friends, but it was leaked and had more than 15 million views before it was taken down.
It has since been posted on the group's Facebook and picked up another five million views.
