The pop band, known for their hit “Stressed Out,” released the song “Level of Concern” in April. Two months later, the duo announced that they were making what they called a “never-ending” music video for the song, using content that fans would upload onto a website.
The final product was a continuous live stream on YouTube. The song would play on a loop, and every time the song began again, new fan videos would appear, creating the intended “never-ending” music video.
But it did, eventually, end. After a whopping 117 days 16 hours 10 minutes and 25 seconds — beginning on June 21 and ending on December 16 — the group pulled the plug, and the Guinness World Records announced their feat.
Previously, the record was held by Pharrell Williams, who created a 24-hour music video for “Happy” back in 2013.
