The music video for "10 Years" was released on Daði Freyr's YouTube channel on 29 March 2021, and was directed and produced by Guðný Rós Þórhallsdóttir. The music video begins with Daði watching "Think About Things" in his room when suddenly, the Mayor of Iceland, played by Ólafur Darri Ólafsson, calls Daði for help. He says that a new monster has emerged in Iceland is heading towards Reykjavík, and they have done all they can to stop it, to no avail. He goes on to say that the only hope to stop the monster now is Daði's "sweet, sweet dance moves" and to gather up the rest of the Gagnamagnið. Daði agrees to help, and sounds a siren.
Meanwhile, the Gagnamagnið are all together, playing video games (a game made by Daði himself, Daði and Gagnamagnið: Think About Aliens!) and are cleaning up the room when the alarm sounds. The screen goes to black, and 10 Years starts to play. Daði runs to the room where the Gagnamagnið where they rush to devise a plan to defeat the monster. The group dress up for battle, instruments and all, and fly to the monster with jetskis. When they arrive, the monster is shown to be destroying houses in the area. Daði is now faced with the monster, and is nervous. They do the 10 Years dance to gather up energy. Once done, they fire a laser, but it backfires as the monster uses the energy to fire it back at the group. The group survives by Daði's shield, and flee. Meanwhile, the monster decides to destroy a farm. The group head to a secluded place in the mountains, and team up to create a robot to defeat the monster. The group once again performs the 10 Years dance, to finally defeat the monster. The credits show the monster dancing in the mountains.
