Florence + the Machine can pat themselves on the back as they have scored their first No.1 hit in their native U.K. The song 'Spectrum,' taken from the group's second studio album 'Ceremonials,' knocked off the boys in Maroon 5 for the top spot on the chart.

According to the BBC, Florence + the Machine sold 64,816 copies of 'Spectrum' to become the best-selling single of the week. The band came close to reaching the No. 1 spot with their 2009 hit 'You've Got The Love,' which was a cover of the 1986 the Source and Candi Staton track.

'Spectrum' debuted at No. 104 on the U.K. Singles Chart but got a significant boost after Scottish DJ Calvin Harris remixed the song. A video directed by David LaChappelle and John Byrne was released in May -- you can watch it here.

This should be comforting news for singer Florence Welch, who was forced to cancel performances at Spain's Benicassim and the Optimus Alive festival in Portugal due to vocal injury. “Seriously I felt something snap, it was very frightening,” Welch tweeted. Florence + the Machine will rest up this week before returning to the stage July 20 in British Columbia, Canada.
