Never Say Never-[永不言败]

"Never Say Never" is a song by Canadian recording artist Justin Bieber. The song serves as the theme song for The Karate Kid (2010), and features rap interludes from the film's star, Jaden Smith. It was originally a risque demo with sexual lyrics performed by American singer Travis Garland, it was written and produced by The Messengers, and Omarr Rambert. However, for unknown reasons, Bieber was tapped to record the song for the film. He re-wrote the song with The Messengers, Rambert, Smith, and his vocal producer Kuk Harrell, to feature inspirational lyrics to foil the film's theme. The song contains R&B and pop elements while merging hip-hop. The song was released for digital download in the United States on June 8, 2010. The song was later included as a track on the remix album My Worlds Acoustic (2010). To promote Bieber's 3D concert film of the same name, the song was released as the lead single from Bieber's second remix album, Never Say Never: The Remixes
