"The Voice": Pre-debate battles feature pop music and a steal

Tuesday's episode of "The Voice" led straight into the presidential debate with an hour's worth of pop music, including a dramatic steal and a battle between two 17-year-old singers.

Part four of the battle rounds continued on NBCs' talent competition as celebrity coaches Blake Shelton, Christina Aguilera, Cee Lo Green and Adam Levine were forced to eliminate more of their team members.

Liz Davis vs. Nicole Johnson for Team Blake

Liz Davis and Nicole Johnson got the night rolling with Miranda Lambert's "Baggage Claim." Aguilera described their voices as "strong," while Levine thought their performance was "great." Shelton chose Davis because she's a bit more experienced.

Alessandra Guercio vs. Kayla Nevarez for Team Adam

Tuesday also featured the battle of the 17-year-old singers: Alessandra Guercio versus Kayla Nevarez, who sang "Wide Awake" by Katy Perry. After their performance, Levine said he was disappointed in Guercio's lack of confidence; he chose Nevarez. But that left Guercio up for grabs, and Aguilera snatched her in a steal. "Let's work on that confidence thing," Aguilera said.

Emily Earle vs. MacKenzie Bourg for Team Cee Lo

Emily Earle and MacKenzie Bourg tackled "Good Time," by Owl City featuring Carly Rae Jepsen, in hopes of winning over Green. As for Levine, he thought their chemistry was "uncomfortable," while Shelton said MacKenize had a "strong" voice. But it was up to Green to decide. He went with MacKenzie.

Ben Taub vs. Mycle Wastman for Team Cee Lo

Pop vocalist Ben Taub took on Green's "Forget You" with soul singer Mycle Wastman. Green chose Wastman.

Adanna Duru vs. Michelle Brooks-Thompson For Team Adam

Adanna Duru and Michelle Brooks-Thompson performed Beyonce's "Crazy in Love." Levine said Duru has a career ahead of her, but he picked Brooks-Thompson to advance.

Beat Frequency vs. Laura Vivas for Team Christina

Aguilera paired up duo Beat Frequency with Latin singer Laura Vivas for a rendition of Lady Gaga's "Poker Face." Vivas won.

The battles continue for one more week before the knockout rounds begin. The next episode airs Monday at 8 p.m. ET.
