Meanwhile Ed Sheeran's Sing - expected to be number four - was predicted to be the most streamed track of the week with 13% of his sales accounted for through online listening, also possibly given a boost by his appearance at Glastonbury.
Other acts to have benefited from performing at the festival include country star Dolly Parton whose 1973 single Jolene is on course to make the top 40.
The official singles chart will see online streaming from services such as Spotify and Deezer included for the first time.
The move to include streamed songs alongside downloads and physical sales follows a massive surge of interest in audio streams over the last 12 months, the Official Charts Company said.

Listeners will need to have streamed a song for a minimum of 30 seconds for it to count, with 100 streams of a song counting as one sale.
Brit Award-winning band Bastille's song Pompeii has been streamed more than any other track in the UK, with more than 26 million plays.
Asked about the news music streaming will be included in the Official Singles Chart, Bastille frontman Dan Smith said, "I think for the charts to be fair it has to reflect how people digest music."
The Official Charts Company said "the time is now right" to add music streaming to the UK singles chart for the first time.
Chief executive Martin Talbot said:
Audio streaming has grown at an extraordinary rate over the past year - and the time is now right to take this important step.
Just as it [the Official Singles Chart] has evolved through the years to reflect the most popular music in the UK, from 10-inch to seven-inch, vinyl to cassingles, CD singles to downloads, this is the latest stage of that progression.
Music streaming on services such as Spotify and Napster will be included in the UK singles chart from July 6.
The Official Charts Company will weight the streaming so that 100 plays amount to one physical sale to differentiate between buying one specific track and merely choosing to play it as part of a general service.
So far this year, the average weekly figures volume of streaming is 70 times greater than the combined sales of downloads and physical singles.
