It's all up to the audience now.
The final four contestants on The X Factor sang their hearts out Wednesday night for a spot in next week's final, and audience votes alone will determine which act gets eliminated on Thursday night and which three will advance - with no sing-off or judges' votes to decide. Additionally, the show isn't going to reveal the rankings of the Top 3, meaning that viewers won't know who the frontrunner is heading into the finals.
For the second week in a row, the acts each performed two songs - one of their choosing and one selected by them and their mentor (though Demi Lovato is the one judge with no contestants remaining). Here's a breakdown of each performance.
