A 2013 Katy Perry single that topped charts across the world and then settled into a second career as background music for anything triumphant — sports montages, weight-loss posts, leaving parties. The record's entry for a pop song that became a stock empowerment cue.
The record notes only that it became globally famous and topped charts in many countries. Its afterlife is the more interesting part: it stopped being a song and became a soundtrack option.
Playing at the finish line of a charity 10k in 2015, and again at the same event in 2016, presumably from the same playlist file.
A colleague used it under a leaving video in 2014. Nobody found it funny. Everybody found it correct.
Where did you see it, and when? A date and a source that still resolves.
