Online music plays are to be included in The Official Singles Chart for the first time.
The Official Charts Company has announced the weekly chart list will now factor in the number of times a song has been streamed on the internet.
The new system will count every 100 plays as the equivalent of one record sale and will include singles played via online music services Spotify, Napster, Deezer and Xbox Music.
The Official Charts Company's chief executive Martin Talbot said: "The Official Singles Chart is the definitive measure of Britain's music tastes.
"Just as it has evolved through the years to reflect the most popular music in the UK , from 10 inch, to 7-inch, vinyl to cassingles, CD singles to downloads, that is the latest stage of the progression."
The move has been welcomed by indie band 'Bastille' - whose track 'Pompeii' has become the most streamed track in history.
The group's frontman Dan Smith told The Mirror newspaper: "I think streaming going into the chart is definitely a good thing.
"For the charts to be fair they have to reflect how people digest music."
The first Official Singles Chart to incorporate streams will be unveiled from 4pm until 7pm on Sunday, July 6 by BBC Radio 1 and the full Top 100 will be published on OfficialCharts.com at 7pm.

Daniel Radcliffe wants to play Batman's sidekick Robin.
The 'Harry Potter' star believes he would be the "perfect" choice to take on the role of the superhero sidekick in the rumoured upcoming 'Batman' reboot starring Ben Affleck.
When asked which movie franchise he would consider starring in, he told Buzzfeed: "Batman. If they reboot that again, I'll do that, too.
"It's happening isn't it? With Ben Affleck. I could be Robin. I'm perfect."
Affleck, 41 - who is to make his debut as the Caped Crusader in 'Batman v. Superman: Dawn of Justice' next year - will reprise the role in 'The Justice League' in 2017 and it's now been reported that he's landed his own solo outing, set for 2019.
According to Latino Review, the film is speculatively called 'The Batman' and is being planned for four years' time because of Affleck's busy schedule.
Meanwhile, Radcliffe, 24, is also said to be interested in joining the legendary 'James Bond' franchise as an "evil mastermind".
A source said previously: "Daniel thinks he would be an excellent villain in the Bond films. He loves the franchise but admires the villains as much as Bond.
"He feels he could appear as a modern bad guy, an evil mastermind who wants to take down MI5."

June Brown has vowed to never quit 'EastEnders'.
The 87-year-old soap legend says she is more likely to "die first" than quit her role as Walford busybody Dot Branning.
She said: "I'll probably die first and they'll take me out in a box."
Devout Christian June relayed her wishes for her burial, explaining: "I want to be buried at sea. I don't want people talking about me. I want a plain ordinary service and [to] be dropped at sea ... and I want to be in a white shroud, I don't want to be dressed up looking as if I'm going out for dinner and I don't want any make-up on."
The actress, who has played soap icon Dot since 1985, also confessed she often changes her character's lines to reflect her own Christian views.
Appearing on BBC's 'Sunday Morning Live', she said: "I think you should play characters as they are written but the scriptwriters don't always write the prayers and behaviour of a Christian into it.
"I can tell if a script has been written by an agnostic or atheist, and I'm afraid I have changed the scripts. My faith has changed Dot. She was a 'kindergarten Christian' - someone who thinks of god as a bearded man in the sky - but I have strong faith.
"I will fight to keep Dot how she is now because I am 87 and I say what I think."

Cheryl Cole wants a Spice Girls versus Girls Aloud week on 'The X Factor'.
The 30-year-old pop star would love to see a battle of the girl bands during the live shows, pitting her band's back catalogue against fellow judge Mel B's hit songs with the Spice Girls.
She told the Daily Mirror newspaper: "You know what, it's a really good idea. I'm going to put that to the producers and I'm sure we can figure something out."
Cheryl and Mel have both ruled the music charts with their respective groups and sold millions of records.
Girls Aloud had four number one singles, including their debut track 'Sound of the Underground', and earned a BRIT Award for 'The Promise'.
Meanwhile, the Spice Girls are one of the biggest selling bands of all time with 80 million record sales around the world and nine number one singles in the UK.
While viewers may be hoping for a rivalry between Cheryl and Mel, it seems the 'Crazy Stupid Love' singer is eager to avoid any drama on the panel this year.
A source previously said: "Everyone thinks there is some huge beef between Cheryl and Mel but there isn't.
"Cheryl is happy it is another woman [on the panel] and she thinks she will work well with Mel as they are both very feisty.
"Cheryl is just going to focus on the show and wants to find the winner."

Brooke Vincent finds it hard to meet men because they think she's a lesbian in real life.
The 'Coronation Street' beauty, who plays lesbian Sophie Webster, admits she doesn't get much attention from the opposite sex following her split from footballer Josh McEachran as guys assume she only likes women.
She said: "That's the first question a lad will ask me, 'Are you really a lesbian?' "
The 22-year-old actress, whose character is in a serious relationship with Maddie Heath (Amy Kelly), admits she worried how viewers would react to her storyline but is pleased with the positive impact it has had on young lesbian viewers.
She explained to The Sun newspaper: "I was worried how people were going to respond because I was the first 'Corrie' lesbian. I was the first soap lesbian, really. I'm probably the first proper one.
"A lot say, 'Oh, my gran understands now, because you're a lesbian on 'Corrie' and she watches 'Corrie'.'
"It's normally the older generation that struggles with it because it was not around in their day, never heard of, and you couldn't say this and couldn't say that."
Brooke finds the positive effect incredibly rewarding and thinks her plot has been an "amazing experience".
She added: "It's just knowing you're helping that one person, it makes such a difference. So many people tweet me and say, 'Thank you for this.' "

Brendan O'Carroll was the "golden boy" in juvenile detention.
The creator and star of 'Mrs. Brown's Boys' has confessed he was sent to a youth detention centre in Dublin, Ireland, after he was caught stealing a roll of sticky tape and a bicycle bell as a youngster, but his ability to read Latin made his three-week stay much easier.
Brendan said: "Well, that made me the golden boy! I was up every morning at half-six for Mass and I got a pretty easy ride of it at the end of the day.
"A lot of people got a much tougher time than me in there."
The 58-year-old funnyman - who admits his famous character Agnes Brown is based on his mother and other strong women he grew up around - was celebrating his birthday on the day he received his court sentence and reveals his mother didn't let it ruin his day.
He told the Daily Mirror newspaper: "The morning I went to court, it was my ninth birthday. I was in my suit for my birthday, the suit I'd worn to one of my brothers' or sisters' weddings, and my mother took me into town. On the way we stopped by the court.
"When we came out of court, I said, 'How did it go?' She said, 'We'll talk later.' We had a great day ... she brought me to Bewley's [coffee shop] to have coffee, she put down a plate of éclairs, and I ate eight éclairs!"
He added: "That night she told me, 'Listen, you've got to go the police station tomorrow, you've got to go away.' "

Avril Lavigne would "love to" have children.
The 29-year-old singer - who is married to Nickelback rocker Chad Kroeger - definitely wants to have kids one day, but insists she is currently too busy with her work.
She said: "I'm really focused on my career at the moment.
"Down the road, I would love to be a mom, just not right now."
The 'Complicated' hitmaker thinks it is "crazy" she will turn 30 in September, but while she still feels young, she admits she has experienced a lot.
She said: "I feel young but yeah I've lived a lot. I've been doing this music career for over a decade and travelling non-stop. It's kind of crazy. I don't have a plan yet (for my 30th birthday) ... but I'm hoping for a big party."
These days, Avril admits she finds herself returning home to see her family a lot more than she did in the early days of her career.
She explained in an interview with QMI: "When I was a younger, like a teenager on the road, they're not necessarily where your priorities are at.
"But yeah, as I've gotten older I've realised how closer I am to my family more than ever. That's just a part of growing up and stuff like that. I've spent a lot of my time in Los Angeles and just really missed my family and was like, 'You know what? I want to spend more time with them 'cause they're the people at the end of the day that are really there for me, that have my back.' "

Kim Kardashian saves her "twerking" for "the bedroom".
The brunette beauty - who has 12-month-old daughter North with husband Kanye West - told her family she no longer goes to clubs but saves her raunchy dance moves to use in private.
She said: "My twerking skills are for the bedroom, not the club."
Kim was speaking with her mother Kris Jenner, sister Khloe Kardashian and half-sister Kendall Jenner during a Soul Cycle class on last night's (22.06.14) episode of 'Keeping Up with the Kardashians', and during the workout session, the showbiz matriarch was the subject of a number of mean comments from her younger daughter.
As Kris started clapping and dancing to the music, Kendall blasted: "Do you always have to be the centre of attention? It's so annoying
"Eww mom, you're so embarrassing, you need to act your age."
She then muttered: "Desperate f***ing w***e."
Kris, 58, didn't appear to hear the comment and later told her daughters: "This reminds me of being in the club, for real. I love the music, I love the energy, everyone's so excited."
Kendall snapped: "Why are you going to clubs? This is so embarrassing."
Kris said she simply liked "being out an about", prompting the teenager to brand her an "embarrassment to the family".
While Kim stayed silent, Khloe laughed at Kendall's mean comments and later criticised her mother for needing more attention following her split from husband Bruce Jenner last October.
She said: "Ever since Bruce moved out, my mom needs so much attention. But sometimes it's like, OK, relax, chill. Everyone knows you're here."
The sisters eventually saw they had been unfair and later apologised to their mother.

Shooting on Will Ferrell's new movie has angered New York residents.
The 46-year-old actor is currently filming 'Sleeping With Other People' - which is is producing along with Adam McKay - with Amanda Peet, Natasha Lyonne and Jason Sudeikis and householders in the Upper West Side neighbourhood are annoyed by the fleet of "enormous trucks" that are blocking their driveways.
A source complained: "They've taken up three quarters of the block with 10 enormous trucks. The traffic here is like the president's in town."
According to insiders, Will was even booed when he left the West 81st Street property - which is Rosie O'Donnell's former home - where filming is currently taking place.
The source added to the New York Post newspaper's Page Six column: "[When they came out of the house], there was a mix of cheers and boos. The cheers were mostly for Natasha Lyonne."
The 'Anchorman' actor - who is father to Magnus, 10, Mattias, seven, and Axel, four, with his wife Viveca Paulin - recently admitted he is obsessed with children's building toy Lego.
He said: "I have had moments where I have sat down to help my son build the Millennium Falcon [craft from 'Star Wars'] and have literally told him to leave the room because I have to finish this one part. He can join me later. And I literally build it like for an hour. But then it's like, 'My God, what am I doing?' "

Keira Knightley "nearly killed" her husband when he tried to teach her to play guitar.
The stunning actress, who had to learn to play the instrument for her role of Greta in the film 'Begin Again', admits it was a bad idea to let her husband, James Righton from indie band The Klaxons, teach her the basics.
Asked if it was fun being taught by James, she said: "No, I nearly killed him. Don't get your spouse to try to teach you a musical instrument. It's just a terrible idea. I wonder if there's ever been a death by guitar? Do you think anybody's ever done that? I did actually learn to play, but I can't sing and play at the same time."
The 29-year-old actress claims she doesn't know "anything about music at all" and has to concentrate on songs to be interested in them.
She said: "I never really listen to it [music]. If it's on in a room, I can't really hear it. I don't have that sort of brain. And that's another reason I was so interested in doing this film. I'm married to a musician, my best friends are completely obsessed with music, my brother was in bands - it completely surrounds me, but I really have to concentrate to pick it up. If I'm really drunk, then I'll dance, but I won't know what I'm listening to."
The 'Anna Karenina' star appears alongside Maroon 5 singer Adam Levine in the new movie, and Keira claims he was worried about his performance because he is relatively new to acting.
She told HELLO! magazine: "Adam kept saying that he was nervous, but I can't imagine Adam nervous. He has the most incredible confidence. He's a proper entertainer."

Tom Cruise could make a cameo in 'Star Wars: Episode VII'.
The 51-year-old star is close friends with the film's director J.J. Abrams - who helmed 'Mission: Impossible III' - and the pair reportedly met over the weekend to discuss a role for the A-lister.
A source told The Sun newspaper: "Tom has been in London for over a week and met up with J.J. and some other people from 'Star Wars' at the weekend.
"On Saturday evening five of them met up for dinner and drinks at the Belgravia Hotel. J.J. loves working with Tom whenever he gets the chance."
The sci-fi production could use some star power after leading actor Harrison Ford, who reprises his role as Han Solo from the original trilogy, was rushed into surgery last week following a freak accident on set.
The 71-year-old actor is recuperating after breaking his leg and won't be available to film for several months.
The source added: "Losing Harrison is going to set things back a little scheduling wise and there's some time to play around with."
Cruise recently starred in a sci-fi summer blockbuster 'Edge of Tomorrow', which earned critical acclaim, and is next set to film the fifth instalment of the 'Mission: Impossible' franchise.
'Star Wars' is currently filming at Pinewood Studios in Buckinghamshire, England.
It's rumoured 'Looper' director Rian Johnson could be in line to write and direct the follow-ups, 'Episode VIII' and 'Episode IX'.

Kate Bush spent three days submerged in water in a flotation tank to create special effects for her live shows.
The 55-year-old singer, who will take to the stage for 22 concerts at the Eventim Apollo in Hammersmith, London later this year, has hired a movie tank at Pinewood Studios, where she has been practicing a 'lost at sea' scene in which she is rescued by a helicopter.
A source told the Daily Mirror newspaper: "During her concerts there will be lots of footage and special effects.
"Kate wants the show to be out of this world and hired the underwater stage which is fitted with a wave machine and special lighting at Pinewood Studios.
"She spent three days in the tank re-shooting scenes and performing her songs. She wanted to create the effect of her floating in the ocean, lost at sea.
"The footage ends with her singing 'Hello Earth' and being saved by a helicopter.
"Special technicians re-created the helicopter by using ceiling fans."
The recording was given the code name 'Navy Blue' and the pop star performed hit songs including 'And Dream of Sheep' and 'Wake Up'.
Despite being underwater, the crew working on the scene were reportedly "gobsmacked" by how powerful Kate's voice was.
One staff member said: "We were all brought to a complete standstill as she sang, her voice is absolutely incredible, it was completely flawless. It was the most beautiful thing some of us had ever heard.
"She may have aged but her voice hasn't changed."
Kate has reportedly "thrown everything" into the highly-anticipated live shows and millions of pounds are being spent on special effects, costumes and staging.
The gigs, which sold out in just 15 minutes, are kicking off on August 26, with seven new dates at the end of September and in October added just last night due to massive pre-sale demand.
Kate's announcement comes after her 'The Tour of Life' shows in 1979, which had until now been the only concert tour of her career.
The six-week tour took her around Britain and mainland Europe and ended at the Hammersmith Odeon - now called the Hammersmith or Eventim Apollo - the venue she has chosen to return to.
