The Voice semi-finalist Leah McFall sold 20,000 copies of her I Will Survive over just one day.
We told on Sunday how Leah charted in the Top 20 in this week's official charts with her cover, just a day after the song went on sale Friday evening.
Leah sold 19,213 copies of the track between Friday evening and the close of the chart week on Saturday night, placing her 16th in the charts.
Of the twelve singers who competed in Friday's first live show, three others made the official Top 200 by Sunday night.
Team Tom's Mike Ward, who wowed with a country take on When I Was Your Man, sold 2,473 copies to land just outside the Top 100, while Team Danny's two remaining artists Andrea Begley and Karl Michael sold 1,687 and 1,445 copies respectively, charting at 150 and 182.
The tracks have continued to sell throughout this week, with Leah remaining in the Top 5 of the iTunes and Amazon download charts ahead of Sunday's next official run down.
It's perhaps no surprise then to learn that bookies are already beginning to declare Leah the winner of this year's series.
Jessica Bridge of Ladbrokes said: "It's game over as far as we're concerned, the rest of the series should merely be a walk in the park now for Leah."
This weekend's Voice UK semi-final will see another four acts - one from each team - cut, and this week it'll be the public alone who decide, with no more fast passes for the coaches to give out.
Saturday night's second live show will also see a performance from Avril Lavigne, singing her new track Here's To Never Growing Up.
