Mike Posner's I Took A Pill in Ibiza tops singles chart
Mike Posner has topped the UK Singles Chart with I Took A Pill In Ibiza after one of the closest races in nearly a decade.
In a nail-biting finish, the US singer has overtaken Lukas Graham by 261 combined chart sales, the Official Charts Company said.
It's the narrowest margin between the top two since summer 2007, when Timbaland and Keri Hilson's The Way I Are beat Kate Nash's Foundations to number one by a mere 16 copies, knocking Rihanna's Umbrella off the summit in the process.
The Danish band may have fallen to number two after five weeks at the top, but 7 Years is still the most streamed track of the week, notching up over four million listens.
Zara Larsson's Lush Life has reached a new chart peak, climbing one spot to number three, while Fifth Harmony's Work From Home powers up seven spots to number four.
Rounding off the top five this week is Rihanna's Work. The Bajan star kicked off her Anti World Tour in Florida last weekend.
Highest new entry this week goes to Ariana Grande's Dangerous, which is new at number 17.
The star showed off both her knack for celebrity impressions when she appeared as a guest presenter on long-running US series Saturday Night Live last weekend.
Selena Gomez's Hands To Myself has zoomed up 11 places to number 21, while her good friend Joe Jonas and his band DNCE have climbed 16 places with Cake By The Ocean. The track is at number 26 this week.
Former One Direction star Zayn Malik has scored his second solo Top 40 hit since leaving the boyband. Like I Would has gone straight in at number 30.
On the Official Albums Chart, there is no topping Adele. The Oscar-winning singer's smash hit long-player 25 is at number one for a second straight week, its 11th in total.
The When We Were Young star's album has outsold its nearest rival by over 10,000 copies.
It is an especially impressive feat because 25 is not available to stream: the Londoner has the number one spot on physical and digital sales alone.
Adele's closest competition is Justin Bieber who has climbed one place to number two with Purpose.
Despite being the first artist to hold number one, two and three at the same time on the Official Singles Chart with tracks from Purpose, it is yet to become Bieber's second number one album.
Jess Glynne's I Cry When I Laugh falls one place to number three, with David Bowie's Best of Bowie at number four and Coldplay's A Head Full Of Dreams one place below the late rock star.
New entries on this week's Album Chart include metalcore group Killswitch Engage who have their first UK Top 10 album with Incarnate.
The seventh studio album from the American band has bested 2013's Disarm The Descent which peaked at number 15.
Jeff Buckley's latest posthumous release is You And I, a new entry at number 16. The American singer-songwriter and guitarist drowned in 1997 while taking a swim in the Mississippi River.
Other new entries come from Norwegian singer Aurora (of the John Lewis advert fame) who is at number 28 with All My Demons Greeting Me As A Friend.
Former Australian Idol runner-up Matt Corby's Telluric is at number 36.
The week's highest climber is from Walking On Cars, whose debut album Everything This Way has jumped 59 places to 39, over two months since it made its Top 100 debut.
