Former X Factor winner James Arthur is battling for the number one spot in the charts with his comeback song Say You Won't Let Go.
The track has leapt 23 places to number two in the midweek chart, and is the most downloaded track of the week so far.
Current chart-topper Closer by The Chainsmokers and Halsey is still leading the way, and is 10,000 combined sales ahead of James's song.
Say You Won't Let Go is James's first single release since 2014´s Get Down.
DJ Snake and Justin Bieber's Let Me Love You is at number three and Major Lazer's Cold Water is in fourth place, said the Official Charts Company.
Calvin Harris is on track for a top five debut as his new single, My Way, is currently number five.
In the Official Albums Chart, Bastille's latest record, Wild World, looks set to hang on to the top spot this week.
At the midweek stage, the band are fending off competition from Led Zeppelin's Complete BBC Sessions album - a collection of the group's five live sessions recorded in 1969 - to hold their place at the top.
The Beatles' Live At The Hollywood Bowl is at number three and Nick Cave and The Bad Seeds' Skeleton Tree is at four.
The top five is rounded out by Ward Thomas - twin sisters Catherine and Lizzy Ward Thomas - with their album, Cartwheels.
Meanwhile, Skepta's Konnichiwa is surging back up the charts after bagging the 2016 Mercury Prize last week. Currently up 44 places to nine, the record has seen a 50% combined sales uplift since his win.
Konnichiwa entered the Official Albums Chart at two when it was released back in May.
