Cassette players were an everyday part of music listening from the late 1960s through the 1990s, and the sound of ejecting a tape became shorthand for finishing a side, swapping a mixtape or rewinding a memory. As tapes returned as a nostalgic aesthetic online, creators began using the eject click in edits, lo-fi videos and retro-themed content to signal a change of mood or era. It remains popular because it is short, instantly recognisable and carries a strong association with analogue music culture without needing any explanation.
