PaRappa the Rapper is a rhythm game developed by NanaOn-Sha and first released in Japan in 1996, built around rapping through everyday challenges. The 'I Gotta Believe' line captures the game's encouraging, try-again spirit, which helped it become a cult favourite long after its original PlayStation run. Clips from its songs have circulated for years in fan edits, remixes and reaction videos, keeping the music familiar to new audiences who may never have played the original. That mix of nostalgia and optimism explains why the hook still appears in modern edits.
