'The Voice' NBC Season 7 Coaches Gwen Stefani & Pharrell Williams Premiere New Single 'Spark the Fire' Live (VIDEO)

"The Voice" Season 7 continues on NBC on Monday night with performances from the Top 8. The final eight contestants are Team Adam: Matt McAndrew, Chris Jamison, Damien, Team Blake: Craig Wayne Boyd, Team Pharrell: Luke Wade, DaNica Shirey and Team Gwen: Taylor John Williams, Ryan Sill. I am personally pulling for Luke Wade and Taylor John Williams currently. 

Along with the performances from the Top 8, a few of the coaches themselves will be hitting the stage. New coaches this year, Pharrell Williams and Gwen Stefani will be premiering the new song that they wrote together called "Spark the Fire". You can check out the video above of Gwen and Pharrell talking about how the song came together and what it means to them.
