Grand Theft Auto IV was released by Rockstar Games in 2008 for PlayStation 3 and Xbox 360, later coming to PC, and its main theme became closely tied to protagonist Niko Bellic's arrival in Liberty City. The sombre, Eastern European-influenced melody matched the game's darker, more grounded story compared with earlier entries. As clips circulated on YouTube and soundboards, the short theme became shorthand for gritty city drama and gaming nostalgia. It remains popular because a few piano notes instantly signal that tone without needing any dialogue.
