YouTube celebrates 'Bad Guy' hitting 1 billion views, bringing thousands of Billie Eilish fan covers together for an infinite music video

'Infinite Bad Guy' is now live

Billie Eilish: 'Infinite Bad Guy'

Billie Eilish’s chart topping hit, “Bad Guy,” just achieved one billion views on YouTube, her first music video to reach this monumental milestone. Since the song was released in 2019, tens of thousands of Billie Eilish fans from across the globe have uploaded their own versions of “Bad Guy” to YouTube. The covers span nearly every genre, language, and country — ranging from professional to amateur — and from ridiculous to sublime. These covers reveal the very best of the YouTube creator community’s breadth and diversity, and shine a light on Billie’s passionate fans. 

To celebrate one of the most-covered songs on YouTube and the billion views milestone, YouTube and Google Creative Lab have built an infinite music video, "Infinite Bad Guy." This unique AI experiment uses machine learning to bring thousands of covers together, seamlessly aligning them in endless combinations, creating a music video that’s different every time you watch it. 


Bringing a global fan base together

Infinite Bad Guy brings together music fans and creators from around the world, and celebrates the global reach and impact of music on YouTube. From French autoharpists to Japanese rubber chickens, each of the 15,000 “Bad Guy'' covers couldn’t be more different. With approximately 10.5 million seconds (and counting) of Billie fan love, every play creates a never-before-seen and can-never-be-seen-again combination of videos performed by her talented fans from around the world. Mathematically this means 1.46 x 10^100 years of video combinations. Two people wouldn’t see the same sequence twice, from now through the end of the universe.

To create this experience, Google Creative Lab had to perfectly align the audio from thousands of videos with different tempos, instruments, keys, and styles. Conventional algorithms couldn’t do the trick alone, so we turned to machine learning. For videos that deviated from the original track — like acoustic or a cappella versions — we built a neural network that could predict matches between covers and the original. With this data, we were able to line up all kinds of different covers, and switch seamlessly between them.

To navigate through all of these covers, we used the Google Knowledge Graph to find patterns — identifying the different musical styles, instruments, props, and more — that make up the key moments of each video. This allows fans to explore covers that sound or look alike, or sample a little bit of everything. 

In combining all of these elements and more, Infinite Bad Guy was brought to life.
