Fifth week at top spot for surprise Danish hit 7 Years
Lukas Graham's surprise hit 7 Years looks set to take a spot just behind Uptown Funk in the history books.
The Danish foursome's song is on course to spend a fifth week at number one on Friday, making it the longest running consecutive number one since Mark Ronson and Bruno Mars notched six weeks with their spirited dance track.
Justin Bieber achieved the feat of five weeks over November and December 2015, but his victory was split between songs Sorry and Love Yourself.
Coming in at two in the midweek update is Mike Posner with I Took A Pill In Ibiza, which pushes Rihanna and Drake's collaboration Work down to three.
Zara Larsson's Lush Life holds at four while Jonas Blue's Fast Car stays at five.
Also proving its staying power is Adele's 25, which is poised to return to number one in the album charts as she continues her world tour.
25 is yet to leave the top five since it entered in December and has notched an impressive nine consecutive weeks in the prime spot.
Jess Glynne has rocketed from sixth to second place with I Cry When I Laugh, but she's got a huge 27,000 combined sales to catch up to Adele.
Rounding off the rest of the top five are Justin Bieber's Purpose at three, David Bowie's Best Of Bowie at four, and Coldplay's A Head Full Of Dreams at five.
