The change will come into play on Friday as the official singles countdown is revealed on BBC1.

The importance of video in music has come to the fore as Spotify and Apple Music, which were primarily audio based platforms, have introduced video to their offering.
The top ten lists of artists rank differently when measured in views versus sales, with most watched videos showcasing newer artists who have captured and held an online audience.
The top ten UK's biggest selling singles of all time, hitting a million sales include artists such as Elton John and Boney M.
Looking back over 2017 Dua Lipa scores the most viewed video, with over a billion views for 'New Rules,' for a female artist.
Of those views, 60 million have come from a purely UK audience.
However, there was zero recognition for this feat prior to the chart rule changes.
Announcing the changes, Lipa said she was "grateful" for the new rules.
In a video she explained: "Video is really important to me and my career and as artists we can get out music to you."
Official Charts Company chief executive, Martin Talbot, said: “This is a significant step for the UK and ensures The Official Chart continues to be the most comprehensive and trusted chart in the UK, bar none.
"Consumption of recorded music via more than 15,000 retailers, download stores and streaming services of all kinds contribute to the weekly chart countdown."
