"X Factor" brought 120 acts from all over the country to Miami on Wednesday night's episode and only 24 will make it on to the next round - enter "X Factor" Boot Camp.
The first task the "X Factor" hopefuls are given is to sing a song in front of the other contestants, as judge Britney Spears says, "You either stand out or you go home."
The contestants each sing their hearts out with the judges not allowed to comment after each performance.
Los Angeles native Diamond White, 13, kicked off the competition belting Whitney Houston's "I Have Nothing" and the judges seemed to like it.
Jessica Espinoza told the cameras she was very nervous before she sang Mariah Carey's "When You Believe." The performance wasn't her best. Demi Lovato said, "I am pretty disappointed" when the performance was over, remembering her audition.
Boy band Emblem3 sang Goo Goo Dolls' "Iris" and had judge L.A. Reid rethinking the group since its audition when he said they "rocked." After their performance Wednesday night, Reid remarked, "Will you love them 20 songs from now?"
While some contestants soared, others completely choked under the pressure. Johnny Maxwell, 16, couldn't remember any of the words to his song, Diddy's "I'll Be Missing You."
At the end of the show, contestants were divided into three groups. Two of the groups made it through to the next round. Spears got a little teary-eyed as the "going home" group grabbed their bags.
