All the power has been taken from the judges this week, with viewers being allowed to choose songs for each act through a public vote.
Not only that but they also asked a range of celebrities to choose a second song for each contestant to perform and the results are pretty brilliant.
In the public vote, it was decided that Andrea Faustini should tackle Mariah Carey’s Hero for his first song and Sam Smith has revealed that Sia’s smash hit Chandelier will be his second.
“I worked with Sia about six months ago and I remember being in the booth with her and her voice is just ridiculous, and when I heard Andrea’s voice for the first time I remember feeling that same kind of reaction,” said Sam said.
“The song is so difficult to sing but I genuinely from my heart think Andrea can do this.”
Ben Haenow received Thinking Out Loud by Ed Sheeran from the public and Come Together by the Beatles from One Direction, which we think will be an epic performance.
Viewers chose Alicia Keys’ If I Ain’t Got You for Fleur East, while Emeli Sandi picked Tina Turner’s A Fool In Love for her second track.
Former judge Tulisa Contostavlos chose Just The Way You Are by Bruno Mars for Stereo Kicks, while they received Snow Patrol’s Run in the vote.
Finally, Cheryl’s final act Lauren Platt is due to sing Don’t You Worry Child by Swedish House Mafia and Clarity by Zedd (chosen by Little Mix) tomorrow night but she has been ill all week and doubts still hang over her participation in the show.
