John Cena's entrance music, 'The Time Is Now', became his signature sound in WWE during the 2000s, accompanying his walk to the ring as fans reacted with loud crowd cheering. The track's punchy opening later spread beyond wrestling through short meme edits that used it to announce unexpected entrances, surprise appearances and ironic hero moments. Because the music is instantly recognisable even in a few seconds, creators still use it to signal confidence, a comeback or a joke reveal in videos, streams and social posts.
