Final Fantasy XI is Square Enix's long-running online entry in the Final Fantasy series, built around parties of players exploring the world of Vana'diel and fighting together in real time. Its short victory jingle became familiar to players through countless battles, and clips of it later spread through gameplay videos, streams and soundboards as a shorthand for success in any game. It endures because the melody is brief, upbeat and immediately tied to the feeling of finishing a difficult encounter.
