X Factor group Rak-Su have gone to Number 1 on the iTunes download charts.
Studio versions of all the tracks sung on the live shows this year have been released for download via iTunes.
And it allows us all to see exactly how popular the acts are with those who could actually buy their music.
All 12 of the performances from the second weekend are now released onto iTunes to download, as well as Apple Music to stream.
Rak-Su's new original song Dimelo has gone to Number 1 based on iTunes downloads.
"Rak-WHAT?! @RakSuMusic made No.1! And yes, they (and us) are pretty excited about it! 🙌🎤🎉 #Dimelo #XFactor," tweeted the official X Factor Twitter account.
The boys said: "Guys, we are literally so happy, thank you, to everyone who voted for us and thank you to everyone who bought it as well.
"Honestly, for four friends who have been doing this by ourselves for a while now."
They added: "If someone had said six months ago we'd have a song at number one in the iTunes chart we would have just laughed at you. So this is is just.. mad"
Meanwhile the group's song from the previous weekend, Mamacita, has returned to the Top 10 following the latest live show, currently at Number 4.
Elsewhere, Kevin Davy White's cover of Smooth peaked just outside the Top 10 at Number 13 after he performed with the Overs and Girls on Sunday night.
It's not too surprising given that we know both acts topped their respective votes, going head to head in the prize fight which Kevin won.
Elsewhere in the charts, Grace Davies is back up in the Top 20 with her first performance, original song Too Young but her latest performance, a cover of Ciao Adios, is outside the Top 100.
The X Factor 2017 continues this Saturday at 8:10PM and Sunday night at 7:30PM on ITV.
Guest stars will be Harry Styles and Paloma Faith.
There will be a double elimination each night so four acts will be kicked out.
