You'll never believe this, but Chris's intro reel is all about how he's been clean and sober seven months. Apparently he's playing piano while singing in front of an audience for the first time. This ties into how he learned to play piano with his dad, who died a few years ago after Chris promised to make him proud. Okay, after that story, does he even have to sing? I guess so. L.A. has him in a cardigan and necktie and a Richie Cunningham hairdo as he sings the first verse of "No One" by Alicia Keys from the piano, then gets up and joins the dancers for the up-tempo.

Nicole warns Chris that she's going to keep it real, and then says that he doesn't have the best voice but it doesn't matter because of his spirit and how everyone believes. Way to keep it real, Nicole. That was totally bracing. Paula just spews out random drivel just because she has to say something. Simon says Chris delivered just like Simon told him he would have to, and adds that his dad would be proud, making Chris Rene the most recent person Simon has reduced to tears. L.A. says stardom isn't about singing, but lovability, which Chris has. "All we need are the votes." Steve comes out and gives Chris a fatherly hug before doing the voting instructions and going to ads.

Melanie's intro reel is all about her emotional roller coaster from earlier in the competition and then being out of the competition and then back in it and now being in the final four, and her wish to help her family financially, and a fan-Tweet she got from Mariah Carey. L.A. says Melanie's in a rut, which is why Simon has given her something different to do, which, neither he nor Simon seems sure if it'll work.

Melanie's doing the old chestnut "Feelin' Good," and I have to say the gamble pays off big time. Out of her diva comfort zone and doing something a little more bluesy, she just crushes it, earning herself a quadruple standing ovation from the judges' table.

L.A. calls her "the greatest female that's ever graced this stage." He loves the song choice and tells Simon good job. Nicole quotes the lyrics like she loves to do and says that was the new Melanie Amaro anthem, whatever that means. Paula says she's letting go and she loves it, and Simon tells her, "This is why we brought the show to America," and says this is Melanie's bet performance yet. He makes a naked plea for votes, which Steve gives instructions for, but I have a feeling she's safe. "I bet Mariah Carey loved that too," he smarms to Melanie. And what is Twitter for if not for finding out?
