> [Thom Yorke] considered the lyrics "the most upsetting thing I've ever written" > "Fitter Happier" is a short musique concrète track that consists of sampled musical and background sound and spoken-word lyrics recited by "Fred",[17] a synthesised voice from the Macintosh SimpleText application.[75] Yorke wrote the lyrics "in ten minutes" after a period of writer's block while the rest of the band were playing.[65] He described the words as a checklist of slogans for the 1990s, and he considered the lyrics "the most upsetting thing I've ever written",[61] and said it was "liberating" to give the words to a neutral-sounding computer voice.[65] Among the samples in the background is an audio loop from the 1975 film Three Days of the Condor.[75] The band considered using "Fitter Happier" as the album's opening track, but decided the effect was off-putting.[32] ## Related - https://en.wikipedia.org/wiki/OK_Computer
