This sound comes from Rick Astley's 1987 song Never Gonna Give You Up. The track became tied to the Rickrolling prank in the late 2000s, when people disguised links and redirected others to the music video instead. Since then, the audio has stayed popular across forums, short videos and livestream culture because the opening and chorus are instantly recognisable. A longer version like this is useful when creators want more than a quick sting and want the joke to linger for a few extra beats.
