Katy Perry roars to top of charts
American singer Katy Perry has clocked up her fourth UK number one with new track Roar, ending Ellie Goulding's three-week reign with Burn.
Roar sold 179,500 copies over the past seven days, becoming the UK's third-fastest selling single of the year so far, the Official Charts Company said.
"I feel like the UK is so ahead of the zeitgeist," Perry told BBC Radio 1. "They are the zeitgeist!"
Earlier this week Perry ended Robin Thicke's 12-week run in the US.
Roar became Perry's eighth US number one, overtaking Thicke's Blurred Lines, which has dominated the US Billboard Hot 100 this summer.
Roar, taken from Perry's forthcoming album Prism, now sits just behind Avicii's Wake Me Up and Blurred Lines ft TI and Pharrell Williams, as the fastest-selling singles of 2013.
Perry's previous album, 2010's Teenage Dream, saw the singer stack up seven Top 10 hits, and set a new record for the number of top 10 singles from one studio album by a female solo artist.
The artist will close this year's iTunes Festival at London's Roundhouse at the end of this month.
"The UK is where a lot of music trends start. It's where some of the coolest music comes out of, music that's influenced me," Perry told Radio 1's Official Chart Show.
Goulding now slides into second place, ahead of Avicii, Klangkarussell's Sonnentanz (Sun Don't Shine) ft Will Heard and the Cedric Gervais remix of Lana Del Rey's Summertime Sadness, which respectively complete the top five.
Other movers and shakers in the singles charts include You Me At Six, who reached number 11 with Lived A Lie, and new girl group Neon Jungle, who debuted at number 12.
However, the original re-formed Sugababes, now know as Mutya Keisha Siobhan, failed to make the top 40 with their come-back single Flatline.
After only 48 hours on sale, the track debuted at number 50.
In the albums chart, the self-titled debut album from The 1975 went straight in at number one.
The Manchester-based band, fronted by Matthew Healy, son of actors Timothy Healy and Denise Welch, knocked US rockers Avenged Sevenfold's Hail To The King off the top spot after just one week.
Nine Inch Nails' Hesitation Marks took second place, with Brighton duo Rizzle Kicks straight in at number three.
Six years since their last album, Pete Doherty's band Babyshambles have secured their second top 10 album with Sequel To The Prequel, which was a new entry at number 10 this week.
