Nine hopefuls were shown receiving Golden Tickets and making it through to the next round of Hollywood Week.
Jade Flores, a 22-year-old musician from Waxahachie, TX, sang "Strawberry Wine" by Deana Carter.
Lionel thought Jade's ability to entertain the judges was just as powerful as her singing, and Katy agreed she has "the personality to back up" her voice.
"You are a really, really good singer," Luke said, adding that she needed to convince herself of the same.
Christiaan Padavan, a 19-year-old college student from Hampton Bays, NY, performed "Vienna" by Billy Joel.
"We just knew when you opened your mouth that you were going," Katy told the singer.
"You really surprised us. You've got a real serious voice."
Following his great audition, Katy asked Christiaan to belt out "New York, New York" by Frank Sinatra, and the panel absolutely loved it.
Ryan Hammond, a 25-year-old from Modesto, CA, shared a story about how he underwent weight-loss surgery last year and nearly died. There was apparently a hole left in his stomach and gastric acid was leaking into his abdominal cavity, but he survived.

Ryan, who has since lost 170 pounds, sang "Lay Me Down" by Sam Smith.
Katy said she was the best person to audition that day and Luke explained she kept the judges at the edge of their seats.
Lionel said Emma exuded confidence and a comfortable presence onstage, and then she was sent to Hollywood.
Zebulon Spencer, a 27-year-old warehouse worker from Dudley Shoals, NC, sang "Porch Swing Angel" by Muscadine Bloodline.
"You are about [an inch away] from being absolutely incredible," Luke told him. "You have everything country and you have the country soul that doesn't sound forced. Just get a little touch of pain and relaxation in there. I love your tone."
Katy hoped to hear a little bit more grit in his voice.
"I love your potential. It's my favorite country voice that has come through here -- last year and this year," Luke said.
Katy said Zebulon has got something worth working with, and so he earned himself a Golden Ticket.
"The hair started to stand up when you started singing," Richie concluded.
