The X Factor resumed its four-chair challenge Wednesday night, with Paulina Rubio narrowing down her "boys" category from 10 acts to four. Afterward, Simon Cowell began the same process with his "groups" category. Demi Lovato and Kelly Rowland were on hand to offer their critiques, too.
Here's a rundown of what happened on Wednesday night's episode:
The night began with Al Calderon putting a rock edge on the Carly Rae Jepsen hit "Call Me Maybe." Demi thought it was a "little too much" at times, though she did compliment him as well. Simon said what Al lacked in vocals he made up for in charisma. Paulina liked his stage presence and decided to give him one of the four available spots. Calderon would later lose his seat.
Isaiah Alston was dismissed after an uninspired rendition of Whitney Houston 's "Greatest Love of All."
Isaac Tauaefa underwhelmed the panel with his take on Colbie Caillat 's "Bubbly." Kelly thought he seemed uncomfortable on stage. Paulina chose to send him home.
Carlos Guevara turned things around for Paulina with his performance of Bill Withers ' "Ain't No Sunshine." Kelly said he "nailed it." Paulina also loved his interpretation of the classic song. Carlos was allowed to take a seat.
Stone Martin , 14, delivered a slow version of the 1997 Natalie Imbruglia single "Torn." Demi said it was an improvement from his audition. Simon suggested that Stone needs more "swag." Paulina kept Stone around, though his run would soon come to an end.
Chase Goehring , who performed an original song during his audition, tackled "Airplanes" by B.o.B and Hayley Williams . The panel in general questioned the song choice, with Kelly saying she prefers hearing music that Chase wrote. Nevertheless, Paulina opted to assign him to the fourth and final seat, which he would later relinquish.
Tim Olstad belted out Miley Cyrus ' "The Climb." Paulina wondered whether Tim's talents were special enough to advance in the competition. She ultimately switched him into her top four, replacing Stone Martin.
Carlito Olivero covered "Dreaming of You" by Selena , calling it a song that's close to his heart as a Latino. He begged Paulina for the opportunity to remain on the show, and he got his wish. He took away Chase Goehring's spot.
Teenager Timmy Thames selected the Hairspray number "The New Girl in Town." Kelly called Timmy "so stinkin' cute," but she enjoyed his audition more. Simon disagreed, saying it would be "crazy" if he got the boot. Paulina switched Timmy for Tim Olstad, causing the crowd to erupt in boos. She then had a change of heart, bringing Tim back and sending home Al Calderon.
Josh Levi busted a move as he sang an R&B version of Bonnie Raitt 's "I Can't Make You Love Me." Kelly and Simon both described him as a future superstar. Josh took over Timmy Thames' seat.
With Paulina's top four set, The X Factor moved on to Simon's "groups" category.
Girls United brought lots of energy to the stage with Chris Brown 's "Yeah 3x." Simon told the ladies they were well-rehearsed but he's heard a lot better. Girls United ended up earning a seat -- on a bench, not a chair.
The male rap duo Wild Thingz had the goofiest act of the night, prancing around the stage as if each had consumed five Red Bulls beforehand. Simon derided it as "unintentional comedy," but he listened to the "insane part of his brain" and gave them a seat.
Glamour sang the Anna Kendrick hit "Cups ( Pitch Perfect 's When I'm Gone)." Demi thought they weren't ready to take the next step. Though he struggled with his decision, Simon chose to keep Glamour.
The country trio Restless Road closed out the night with Keith Urban 's "Somebody Like You." Demi said she felt chills during the performance, and added that Simon is a genius for putting them together. Restless Road snatched the fourth and final bench.
Simon's six other acts will take part in the four-chair challenge on Thursday night's episode of The X Factor . It airs on Fox at 8 p.m. Eastern time.
