‘American Idol’ Season 15 Spoilers: 2016 Top 4 Song List Revealed; La’Porsha Renae’s Upcoming Rock Performance Called ‘Odd Choice’

On Thursday’s episode of Fox’s “American Idol,” the contestants will once again perform two solo songs in hopes of moving forward in the competition. The first batch of songs the group will tackle will be American rock classics, and the second will be songs by singer Sia.

As with last week’s episode, one contestant will be eliminated during the middle of the show and host Ryan Seacrest will reveal the 2016 top four finalists. Ahead of Thursday’s episode, TV Line has released the list of songs the “American Idol” hopefuls will be singing.

According to the outlet, MacKenzie Bourg will sing Sia’s “Titanium” and, as his rock song, Cheap Trick’s “I Want You to Want Me.” La’Porsha Renae, who has become the season’s front-runner, will take on Sia’s “Elastic Heart” and Bon Jovi’s “Wanted Dead or Alive.” Trent Harmon plans to sing “Chandelier” from Sia’s list of tracks and will also switch gears to sing ZZ Top’s rock hit “Sharp Dressed Man.” Dalton Rapattoni, the resident rocker of the “Idol” group, will perform the Beach Boys’ “God Only Knows” and Sia’s “Bird Set Free.” Finally, Sonika Vaid, who was saved from elimination last week, will sing “Loved Me Back to Life” by Sia and “Because the Night” by the Patti Smith Group.

“American Idol” mentor Scott Borchetta recently dished on the upcoming episode, telling Taste of Country that he’s worried about La’Porsha singing “Wanted Dead or Alive.” Borchetta called it an “odd choice” for the R&B singer and he tried to talk her out of performing it.

“I’m never gonna be comfortable understanding why she would go, ‘I’m a cowboy, on a steel horse I ride,’ ” he said. “It’s like, ‘OK, if that’s the sword you want to take into battle, we will help you as much as we can.”

According to the outlet, Sia and Bruce Springsteen’s guitarist Steve Van Zandt will serve as mentors.

“American Idol” airs Thursdays at 8 p.m. EDT on Fox.
