Plants vs. Zombies 2 is a tower defence game released by PopCap in 2013, and its cheerful title screen music became one of its most recognisable sounds for players. As the game stayed popular on mobile, fans began sharing degraded, compressed versions of the theme online, where the muffled quality itself became part of the joke. These low quality edits are now used in memes and short videos to signal nostalgia, irony or a deliberately scrappy aesthetic, keeping a familiar gaming tune alive long after its first release.
