American Idol 2016 spoilers
See which songs MacKenzie Bourg and the rest of the “American Idol” contestants will sing on episode 21. Fox

The remaining “American Idol” contestants will be taking on a little Bruce Springsteen, some Fleetwood Mac and a Justin Timberlake hit on Thursday’s episode of the Fox singing-competition series. Episode 21 will kick off with the four finalists singing songs they feel represent their hometowns.

Those performances will be followed by an elimination and a Top 3 reveal, before the contestants sing tunes chosen for them by “Idol” mentor Scott Borchetta and judges Harry Connick Jr., Keith Urban and Jennifer Lopez.

According to AmericanIdol.net, Borchetta picked Timberlake’s “Drink You Away” for Trent Harmon. MacKenzie Bourg will tackle Fleetwood Mac’s “Rhiannon” and La’Porsha Renae will sing “Stay With Me, Baby,” by Lorraine Ellison. Rocker Dalton Rapattoni will sing Springsteen's “Dancing in the Dark.”

The judges’ songs haven’t been revealed yet, but three of the four hometown songs have leaked online. Dalton, who’s from Sunnyvale, Texas, will sing “Calling You” by Blue October, while Lafayette, Louisiana, native MacKenzie will perform “Hallelujah” by Leonard Cohen. Trent, a resident of Mississippi, chose Sam Smith’s “Stay With Me” as his dedication song to his hometown.

During the episode, packages will air showing the group’s trip back home, which taped March 26, but a few of them have already teased their visits on Twitter.

Dalton also opened up about his experience on “American Idol,” telling local radio station KVIL that the most memorable part of this season for him was meeting Sia last week.

“I was such a huge fan of her before ‘Idol,’ so when I heard that we were going to be doing her songs, I freaked out,” he said. “That was definitely one of the biggest highlights for me.”

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