Which song was English new wave band Duran Duran's best selling single?

"The Reflex" is the eleventh single by Duran Duran, released worldwide on 16 April 1984. The song was heavily remixed for single release and was the third and last to be taken from their third album "Seven and the Ragged Tiger".

"The Reflex" became the band's most successful single. It was their second single to top the UK Singles Chart, after "Is There Something I Should Know?" in 1983. Topping the chart on 5 May, it turned out to be their last UK no. 1. The single entered the charts in America on 21 April 1984 at no. 46. It became Duran Duran's first of two singles to hit no. 1 on the US Billboard Hot 100 (for 2 weeks) on 23 June 1984 (see 1984 in music), and was a huge hit internationally. (Their only other single to hit no. 1 in the US was the title song to the James Bond film "A View to a Kill").
