Katy Perry attends the Women's March on Washington on Jan. 21, 2017 in Washington, DC.  

"Chained to the Rhythm" drops Friday.

Fans across the world are finding themselves quite unmetaphorically chained to the rhythm -- also the title of Katy Perry's upcoming single -- as they are sharing videos on Twitter and Instagram of themselves standing by disco balls chained to various items in different cities.

But why? The disco balls are connected to headphones that play the new Perry single, ahead of its release on Friday (Feb. 10).

So far, fans have found these disco balls in Chicago, San Francisco, London, Stockholm and seemingly everywhere else. A map that shows the impressive span of this installment can be found here.

Following the song's official release, Perry will debut "Chained to the Rhythm" live at the Grammys on Sunday (Feb 12).
