The X Factor 2016 contestants will be hit with a 'wall of songs' during one of this weekend's bootcamp challenges.
Dermot O'Leary will be shouting BRING ON THE WALL! (we imagine) as the acts face a range of song choices written on pieces of paper and attached to the wall.
The songs range from classic hits - such as Stevie Wonder's Superstition and Ain't No Mountain High Enough - to more recent chart toppers, such as Lukas Graham's 7 Years and Justin Timberlake's Can't Stop The Feeling.
More bootcamp song choices include R Kelly's Ignition, Taylor Swift's Style, Jessie J's Flashlight and the Black Street Boys' I Want It That Way.
But how does the wall work and who will get to sing what? We'll just have to wait until the weekend to see.
In a bumper bootcamp episode on ITV this Sunday night, the remaining contestants will be put through their paces, having to perform once again for the judges in a series of dancing and singing challenges.
Simon Cowell, Nicole Scherzinger, Sharon Osbourne and Louis Walsh will judge the acts as they decide who will earn a coveted place at the Six Chair Challenge and be one step closer to being crowned The X Factor 2016 winner.
"It can or make or break you," warns Sharon to the acts, who also get to enjoy a party at the venue.
But despite the warm welcome, Simon makes it clear that bootcamp is where the show gets serious.
He says: "I don't care how little time you've had to prepare... guess what's going to happen tomorrow? Goodbye."
Dermot is of course on hand to guide us through it all and give out those much needed Dermot hugs.
"There's an awful lot of worried people out there," he tells the cameras.
The X Factor 2016's final auditions air this Saturday at 8PM and the show continues with a bumper bootcamp episode on Sunday night from the earlier time of 7:30PM.
