Billie Eilish's 2019 single Bad Guy has just clocked a billion views on YouTube, and YouTube is celebrating with a nifty digital experiment.
While Billie is currently preparing to release even more new music, it's not every day you reach 1 billion views - and it's memes, mash-ups and covers that have helped give the song its longevity so far.
YouTube has launched Infinite Bad Guy, which they're calling an "infinite music video". It blends tens of thousands of different versions of Bad Guy in sync together. It makes for an endless watch, and it's unique for each viewing. You'll never get the same experience twice.
If you want to check it out, you can go to https://billie.withyoutube.com/ and hit play. That'll kick off the video that started it all, before you go on to choose different thumbnails that take you on a journey and sync up with the song as you click on each image.
