Jet Set Radio is a Sega Dreamcast game first released in 2000, remembered for its cel-shaded Tokyo streets, graffiti crews and rollerblading rebels, plus a soundtrack that mixed funk, hip-hop and electronic music. Its bold, playful attitude has kept it a cult favourite long after the Dreamcast era, and short vocal bursts from its world are now reused as quick signals in gaming edits, reaction clips and short-form videos. This one-word hit works because it carries that whole arcade spirit in less than half a second.
