Plants vs Zombies is a tower defense game released by PopCap in 2009, where players defend a house from zombie waves using garden plants. Its music, composed by Laura Shigihara, became as recognisable as its art style, with short stings marking wins and losses during levels. The victory theme spread beyond the game as players recorded gameplay, shared clips and reused the sound in edits. It remains popular because the melody instantly communicates success to anyone who played the original, even in unrelated contexts.
