This year once again, studio versions of all the tracks performed on the X Factor live shows have been released for download via iTunes and to stream via Apple Music.
And that means we can see exactly how well each act is doing on the charts.
As it stands, 15 of the first round performances have been uploaded. Currently, Molly Scott's cover of BTS' Fake Love is unavailable to download or stream, possibly due to legal rights reasons.
Of the other contestants, leading the way is Anthony Russell and his cover of Julia Michael's Issues. The song was originally performed by Anthony when he auditioned for the show last year, before withdrawing at the Six Chair Challenge.
Back again for 2018, Anthony reprised the song choice for his debut live performance. It's currently the most downloaded of all the tracks from the show, and placing Number 64 in the overall chart after less than 24 hours.
Not too far behind is Shan Ako with her of cover John Lennon's Imagine while Dalton Harris' take on Life On Mars? is a few places further down.
The only other act in the current Top 100 of the overall iTunes chart is Bella Penfold, who performed a cover of Beneath Your Beautiful.
The current least popular track is Acacia & Aaliyah's cover of Finesse, which ranks at Number 1,173 on the overall iTunes chart.

However, downloads and streams don't keep acts in the competition. Instead, it'll be viewer votes that decide who stays.
This weekend is a double elimination. The act with the fewest votes from the public will be instantly eliminated. The next two acts with the least votes will go forward to the singoff. They'll perform again where the judges will decide who to save.
The X Factor 2018 airs at 8PM tonight on ITV with the first round of results. Plus, there will be performances from reigning winners Rak-Su and The Greatest Showman star Keala Settle.
