'American Idol' recap: Auditions continue as Katy Perry addresses Taylor Swift feud

Get all the details from last night's episode.

There were a number of "yeses," but here's a look at just some of the standouts:

New YorkJonny Brenns, from St. Augustine, Florida, says his parents preferred education over music, but his urge to sing was just too strong. In fact, the 6-foot, 5-inch 18-year-old kept his "Idol" audition a secret from them. Jonny’s original tune, called “Blue Jeans,” got mixed reactions from the judges mixed. Katy was a “yes,” explaining that Brenns was “good looking,” and had a “sweet little sexy thing going on.” Luke was on the fence, until Jonny sang a little of Michael Bublé’s “Home” and added a second “yes.” Richie felt the singer was still a little green and voted “no.” Brenns got to call his parents and tell them he’s going to Hollywood, and have Lionel sing a little bit of his hit “Hello” to her over the phone.

Los AngelesEffie Passero, an assistant property manager living in Modesto, California, and a former opera singer backed herself on the piano as she sang her original song, "Troubled Mind." Effie's powerful voice brought the judges to their feet, with Lionel declaring they now had a “secret weapon in our arsenal.” Luke added that Passero -- who sported a punk haircut and numerous tattoos -- had the “whole thing going on.” Katy agreed, adding the singer had a voice they’d been demanding from all the contestants. All three judges shouted in unison, “You’re going to Hollywood.”

Maddie Zahm, a 19-year-old from Boise, Idaho, says music has always been her passion, but a hormone imbalance caused her to gain 100 pounds and took away her confidence. Maddie, who now teaches music to kids with disabilities, was accompanied on her audition by one of her students, a boy with Down syndrome named Marcus. Maddie says his ability to come out of his shell inspired her to do the same. Marcus sat with judges as she performed “New Rules” by Dua Lipa. Then, in a touching moment, he joined her on Katy’s hit “Firework.” Perry noted Zahm had an “incredible set of pipes” and is “a good woman.” Luke said Maddie seemed “a little timid,” at times, before adding, “You got it.” She earned a golden ticket to Hollywood.

Among the montage of artists who didn't make the cut, one provided one of the more awkward moments on Sunday. Bryan asked the hopeful who had influenced him as an artist. "I'm sorry for this Katy -- Taylor Swift -- I love her," he answered, referring to Perry and Swift's alleged feud. "You don't have to worry," Katy replied. "I love her as a songwriter as well."

The "American Idol" auditions continue Monday at 8 p.m. ET on ABC.
