The fanfare comes from Grand Theft Auto: San Andreas, Rockstar Games' 2004 open-world classic, where it played over the Mission Passed screen after every completed mission. Years later the jingle escaped the game and became a universal meme for finishing anything, from exams to chores, with Russian creators pairing it with captions like 'я выполнил' meaning 'I completed it'. Its short triumphant arc makes it perfect for edits, and it still shows up wherever someone wants an instant victory lap.
