Olivia Rodrigo looks set to make it five weeks on top of the UK singles chart with 'Drivers License', according to midweek data from the Official Charts Company.
After the first 72 hours of the week, the track has notched up more than 22,100 chart sales - around 8,500 more than sea shanty track 'Wellerman' from Nathan Evans, which is tracking at two.
Anne-Marie, KSI and Digital Farm Animals' 'Don't Play' is up two places to three, while The Kid Laroi's 'Without You' is holding steady at four.
Digga D and AJ Tracey's 'Bringing It Back' looks set to be the week's highest new entry, sitting just inside the Top 5, while Cardi B has snuck into the midweek Top 20 with her new solo track 'Up'.
Meanwhile, on the albums chart, Foo Fighters are on course to notch up their fifth UK number one, with Medicine At Midnight currently outselling the rest of the Top 10 combined.
