Last night "The Voice" laid the battle rounds to rest with its fourth and final installment. Seven contestants saw their hard work pay off, all advancing and Coach Pharrell Williams seemed more than "happy" to exercise his last steal.

Jeremy Gaynor, 30, and Rob Taylor, 22, of Team Christina were given the daunting task of performing "Animals" by Maroon 5 in front of the band's front man Adam Levine.

"It was nerve-wracking to sing that song in front of the artist," the victorious Rob told HNGN. "We had to kill it, so for Adam to compliment us and share our pain with the song's range, it was an awesome feeling. I felt accomplished."

Jeremy was sent home.

Team Pharrell's Noelle Bybee, 17, and Sawyer Fredericks, 15, delivered a subtly powerful performance of the Creedence Clearwater Revival classic "Have You Ever Seen The Rain." Sawyer owned the performance and won with high praise from Christina Aguilera who admitted, "Sawyer, there's no teaching what you do."
Noelle went home.

"I'm getting over my stage fright and learning stage presence," Sawyer told HNGN of his performance. "Pharrell gives good advice and Lionel Richie was amazing."

Due to time constraints, highlights of 3 performances were shown during the show.

Team Christina's Koryn Hawthorne, 17, won her round against Vance Smith, 22, despite admitting to difficulties performing Ariana Grande's "Love Me Harder."

"Vance and I are both r&b singers," Koryn revealed to HNGN. "So getting a current pop song we struggled, but it worked out pretty well. I am sad people didn't get to see that as I worked hard and it paid off."

Bay Brooks, 17, and Brooke Adee, 16, of Team Blake performed Taylor Swift's "Style."

"It was a harder performance as neither of us are pop singers," winner Brooke told HNGN. "It didn't show we struggled with genre and the song and how Blake really taught us stage presence and how to expand the music we sing."

Lexi Dávila, 17, and Bren'nae DeBarge, 22, battled it out on Natasha Bedingfield's "Unwritten." Lexi was awarded the round.

"It was one of my best performances so far," she said. "I was more open, not shy, and a lot goes to Adam. It was still sad as Bren'nae was a friend and kind of encouraged me when I felt I couldn't do it."

The night's final battle came from Team Blake, who was faced with a difficult choice. Corey Kent White, 20, and Jacob Rummell, 19, both excelled on "I Want Crazy" by Hunter Hayes, and despite the dead even battle, Blake chose Corey.

"The song was still a big challenge for us," Corey revealed to HNGN. "It's not something we'd typically sing, Blake thought it'd be a good fit."

And just when Jacob though he was done, Pharrell stole him.

"I was extremely shocked," Jacob told HNGN. "You start mentally preparing yourself to go home and when Pharrell pressed his button I started shaking and crying - it was amazing."

Next week the knockout rounds begin; steals are back in play and the fun continues (literally) when Nate Ruse of the band Fun offers advice to those competing to become "The Voice" - all on next Monday's episode on NBC at 8 p.m.
