The PlayStation 4 was released by Sony in 2013 as the successor to the PlayStation 3, and its startup sound became part of the console's identity for millions of players. The short chime plays as the system boots, a small audio signature that players heard every time they sat down to play. As clips from consoles spread through streaming, gameplay videos and social edits, the sound began to stand in for gaming itself, even outside PlayStation content. It remains popular because it is instantly recognisable and carries a strong sense of nostalgia for that generation of games.
