The Voice Season 4: The Last Round of Battles Sizzles

Team Shakira: Brandon Roush vs. Shawna P. sang Piece of My Heart by Janis Joplin-- This was really Shawna's battle to lose because she was the more experience and seasoned performer. Brandon put up quite the effort, and I give him props for keeping up with her. Shakira calls the battle eagerness vs. experience and she chooses experience meaning Brandon is sent home.

Team Adam: Duncan Kamakana vs. Sarah Simmons sang Wanted You More by Lady Antebellum-- Blake called Sarah one of his favorite singers in the competition. Usher liked Duncan's confidence, but felt Sarah's voice was incredible. Adam liked Sarah's effortlessness, but praised Duncan's talent. I have to admit, I was hoping someone would steal Duncan, but there was no denying Sarah's raw talent. Her voice and vulnerability were unmatched. She is definitely a threat in this competition.

Team Usher: Michelle Chamuel vs. Chelsea M. sang Titanium by Sia and David Guetta

Final battle of this season was from Team Shakira:
Cathia vs. Mary Miranda sang Antes de las Seis by Shakira-- Adam thought it was beautiful and said if he had to choose it would be Mary. Blake said he loved it and Cathia blew him away. Usher thought it was rather narcissistic for Shakira to choose her own song, but Shakira explained that she wanted to see how each of them would handle it. Shakira said that Cathia has undeniable vocal ability. Mary has a sweet like cotton candy voice, and ultimately she won because of her signature vocal style and charisma. I loved both of them, and I agree there is definitely something about Mary, but a part of me loved the richness of Cathia's voice. Usher came in with the steal for Cathia at the end because she sold him on the song and provided his team with some versatility.
