PewDiePie released Congratulations in March 2019 at the height of his subscriber race with T-Series, framing the track as a tongue-in-cheek congratulation to his rival for taking the top spot. Made with Roomie and Boyinaband, it quickly spread beyond his own channel as fans reused its chorus for wins, milestones and ironic celebrations online. Short clips like this one kept circulating in edits and memes long after the race ended, because the song's bright, self-aware victory tone works for almost any small triumph.
