Melanie Martinez didn't stray far from her trademark soft vocals, but took a slight detour from her usually haunting songs with Cee Lo Green's "Crazy" and "The Show" by Lenka.
Christina Aguilera, whose contestants have all left the show, suggested she try more sultry songs. But Green approved: "In many ways we're cut from the same cloth, honey," he told her. "You did a great job."
Amanda Brown sang "(You Make Me Feel Like) A Natural Woman" by Aretha Franklin and "Here I Go Again" by Whitesnake, proving she could pay tribute to a legend while still belting out the rock hits that have made her a fan favorite. "You're a world class singer," Blake Shelton told her.
Team Cee LoNicholas David sang Earth, Wind & Fire's "September" and Judy Garland's "Over the Rainbow," and pleased the coaches with both performances. "That was magic, and that was beautiful," Shelton said.
Trevin Hunte surprised viewers with a bubbly yet passionate rendition of Katrina and the Waves' "Walking on Sunshine." He also scored rave reviews for Jennifer Hudson's "And I Am Telling You (I'm Not Going)," making a return to his classic soul roots. The performance prompted his coach to ask for "a moment of silence to mourn the loss of all the other competition."
Team BlakeCassadee Pope sang Rascal Flatts' "Stand," before sticking to her pop-rock essence with Avril Lavigne's "I'm With You." She gave a quality performance, but both Levine and Aguilera hoped for something more unexpected from the singer. "I kind of want to see something a little more adventurous from you," Levine said. "I want to see something more different and bizarre."
Accompanied by just a piano, Terry McDermott gave a stripped-down performance of Foreigner's "I Want to Know What Love Is." The simplicity of the set left him nowhere to hide, but his strong voice did not let him down, the coaches said. He also won them over with "Stay With Me" by Rod Stewart. His first performance even had Aguilera, speaking out for Shelton's powerhouse team: "After hearing that," she said, "there's no doubt Blake has the strongest team."
