Angry Birds, developed by Rovio and first released in 2009, became one of the most popular mobile puzzle games of its era, built around launching birds to defeat green pigs. Its level-complete music became closely associated with clearing a stage and earning stars, so players recognised it instantly even without seeing the screen. As gameplay clips, edits and memes spread online, the short fanfare moved beyond the game itself and became a shorthand for any small victory. It remains popular because it is short, cheerful and immediately understood as a success cue.
