Tamashii Revolution

is a song by Japanese band Superfly. It was used as the theme song of the NHK broadcast of the 2010 FIFA World Cup, played during relay clips and highlight shows. It was released as a digital download in Japan on June 18, 2010, and was later included on Superfly's single and cover album release "Wildflower" & Cover Songs: Complete Best 'Track 3' in September 2010. An extended version of the song appears on Superfly's third studio album Mind Travel. Writing and inspiration The song is an upbeat pop-rock song, arranged with a mix of a 1960s-inspired band arrangement and a brass band backing. The lyrics are written in second person, addressing somebody and trying to encourage them. Metaphors, such as facing monsters or "going to an unknown world" are used. The song also mentions that "(the songwriter does not) care about adversity, I'm the strongest when changing." "Tamashii Revolution" was created right before the cut-off date for the soccer theme song's submission, after Superfly vocalist Shiho Ochi and her recording members were not satisfied with any of the other songs they had tried. It was built around a pre-existing chorus lyrical phrase that Ochi had. Originally the songs Superfly were creating had a sparse guitar arrangement, but when they were told that the world cup was taking place in South Africa, the songs had added percussion and a fuller arrangement.
