Gangnam Style was released by PSY in July 2012 and became a global viral hit after its music video spread on YouTube, reaching one billion views later that year. Named after Seoul's Gangnam district, the song satirised luxury lifestyles while its simple dance moves made it easy for people worldwide to copy. It helped introduce many listeners to K-pop and remained a reference point for viral music. Short clips still circulate in memes and edits because the beat and chorus are recognised almost instantly across generations.
