With just one week to get to the Finale, the Top 4 delivered eight title-worthy performances on the Semi-Finals performance show tonight. They sang a Songs To Get Me Into the Finals, which was chosen with the help of their mentor, and the Contestant's Choice, chosen by, you guessed it, the acts' themselves.

Did they choose right?
Will their songs get them to the Finals?
Are Carly, Emblem3, Fifth Harmony, or Tate worth $5 million?

This week, it's all up to YOU because there will be no singing for survival and no judges' decision. It's YOUR vote that counts, so vote, vote, vote! Everything is on the line, and as act-less Demi Lovato said at the top of the show, "This could change their lives forever."

Let's take a look at how the Fight for the Finals played out...

Performance 1: Contestant's Choice

Tate Stevens, Craig Morgan's "Bonfire": Giddy up, L.A. Reid! Loved his black cowboy hat in support of his act! And, loved the truck tire backdrop, the fire, and Tate's fired-up performance. "I don't think it was your best," said Britney Spears to big boos. Demi disagreed. "That was a freakin' amazing performance," she said. Simon Cowell loved it too. "It was one of my favorite performances," he said. "I'm glad I learned to listen because you picked the song and you lit the stage on fire and it's the most fun I've had since I've been doing this show," said L.A.

Carly Rose Sonenclar, Elton John's "Your Song": The 13-year-old chose the song, backed by a children's choir, because her dad would play it a lot. Did she make papa proud? Sure thing! "You did things with that song I've never heard done before," said L.A. "It's still very predictable," said Demi, but added that it was her favorite Carly performance. "I'm confused," Simon said to Demi. "He can't hear. He's really old," fired back Demi. "I'm gonna ignore my little brat," he said, adding that he thought Carly could do better. Brit was a proud mentor.

Emblem3, Peter Frampton's "Baby, I Love Your Way": They took Demi's advice and worked the crowd more in this tribute to the Stromberg boys' mom's favorite song. Did Demi dig it? Yep! She gave them two thumbs up and said they are finally back to what she first loved about them. "If this doesn't get you into the Final, nothing will," said Simon. L.A. called them charismatic and charming and thought it finally was a "$5 million moment." Britney called the performance "special" and said, "It would be unfair to call you a boy band because you're way more than that."

Fifth Harmony, Ellie Goulding's "Anything Could Happen": Looking oh so dreamy in their princess dresses, the fivesome in fourth place sung their little hearts out and worked the props like pros. What props? Butterfly waiters, balloons, a dining table, cakes, tea, and Camila's big bow...oh my! "It was like magic," said Britney. "The dresses, everything, it was so cute," said Demi. "To get into the Final is going to take a miracle," said Simon. "But after that performance, anything now can happen." L.A. called it "the very best vocal performance" they've ever done.

Performance 2: Song to Get Them Into the Finals

Tate Stevens, Clay Walker's "Fall": Ain't no falling for Tate as the country singer delivered a second great performance. "We've seen you hit and miss a lot on this competition and I feel like this was a direct hit," said Britney. Demi said his wife must "feel like the luckiest girl in the world," referencing his dedication of this song to her for their 15th wedding anniversary. "There's about as much chance of you going back to your old job as me flying to the moon tomorrow night," said Simon.

Carly Rose Sonenclar, John Lennon's "Imagine": Can you imagine Carly in the finale after this performance? You betcha! How cool to finally get to see her behind the piano?! "You've taken your artistic credibility up a notch by playing the piano," said L.A. "The only predictable thing about that performance was that it was going to be amazing," said Demi. Simon said he would've kept her at the piano. "It made a beautiful song fussy," he said. "I just didn't like the arrangement. I thought it was overcomplicated." Britney disagreed. "It is time for you to go beyond this stage and complete with the biggest artists," she said.

Emblem3, the Beatles' "Hey Jude": "If you're gonna take on a Beatles song you better nail it," said Demi before the guys performed. Did they? Well, L.A. wanted to "rip them to shreds" for their song choice, but then compared them to "teen heartthrobs like the Beatles." Demi said they have potential, then said it was "amazing." "That was an A-level performance. You guys should take a bow," said Britney. Simon said they "nailed it on both songs." "We're gonna do something great in this world, we need your help," said Drew in a plea for votes.

Fifth Harmony, Shontelle's "Impossible": Closing out the Semi-Finals, the girls added some spice to their performance with a few verses in Spanish! Muy bueno! L.A. said, "The song choice was a little bit lazy because you've done it before." "Boo!" said the audience. Britney said, "I would be really surprised if you guys were here next week." Demi was a little worried about their fate as well. Simon defended the song choice and loved the Spanish parts.
