Task: Question Generation
Input (English): Passage: "Ooh La La", Supernature's opening track, inspired by T. Rex, was chosen as its lead single "because it was up and in your face and it carried on the theme of the glammy, discoey beat from the last album". It was the duo's first song to feature the electric guitar, and received positive reviews, often being noted as a highlight of the album. "Ooh La La" became Goldfrapp's most successful single on the UK Singles Chart to date when it peaked at number four, while topping the Billboard Hot Dance Club Play chart in the United States. The second track, "Lovely 2 C U", received mixed reviews from critics, with one reviewer stating that it was the "worst offender of sounding by-numbers, its lazy glam affectations sounding all the worse amid a chorus striking only in its complete dullness"."Ride a White Horse", the third single, was inspired by the disco era. Like previous singles from the album, the song was another top-20 single in the UK, where it peaked at number 15. The ballads "You Never Know" and "Let It Take You" have minimal background electronics, and were generally well received by critics, who drew comparisons to Goldfrapp's debut album Felt Mountain. Goldfrapp's performance on "You Never Know" was described as "chameleonic" with odes to Debbie Harry and Siouxsie Sioux. "Fly Me Away", another synth ballad, had an associated music video which featured Goldfrapp as an animated doll; the video, however, was never released. Serving as the fourth and final single from Supernature, the song was not heavily promoted and was less commercially successful than the other singles, peaking at number 26 on the UK chart. "Slide In", an electroclash song about sex, and "Koko" were compared to Gary Numan's early compositions."Satin Chic" is a disco song with glam rock and cabaret influences, similar to early Elton John. Cited by Goldfrapp and Gregory as their favourite song on Supernature, it was remixed by The Flaming Lips, and issued as a limited-edition single on 4 September 2006. The 10th track, "Time Out from the World", features an orchestra and whispered vocals by Goldfrapp. Critics liked the song, writing that it was an "exception to the prevailing style of Supernature" due to its "haunting, yet glamorous, atmospherics". The album's closing track and second single "Number 1" is about the importance and meanings of relationships. The song, which is based around a synth and bass arrangement, reached number nine on the UK Singles Chart and number one on the US Hot Dance Club Play chart.
