Monday night is the moment of truth for the three finalists on "The Voice."
Final performances will determine who earns America's vote and wins the competition.
A major consideration for each of the singers is choosing just the right song to perform.
"We went through two different songs and then realized, it's not big enough," said finalist Will Champlin.
The song choice was agonizing for Tessanne Chin as well, and made even tougher by her iTunes topping performance last week.
"Especially, after a song like 'Bridge Over Troubled Water,' you have to follow that carefully," she said.
Chin said the song they settled on scares her, in a good way.
"Because of the person it's done by, we want to do it justice," she hinted, without giving away the song title.
Jacquie Lee, 16, is more than a decade younger than her fellow finalists and stunned to be in the final three.
"I sort of auditioned on a whim So, I wasn't expecting anything," she said.
But Lee found a kindred spirit in coach Christina Aguilera.
"She reminds me so much of myself, just being a sponge every week, taking it all in and getting better and better," Aguilera said.
The challenge Monday is being the best.
After fans vote on Monday's performances, the winner of "The Voice" will be announced in the two-hour finale Tuesday night.
It'll feature performances by Lady Gaga, Celine Dion, Ne-Yo and OneRepublic.
The winner of "The Voice" earns a $100,000 recording contract with Universal Republic Records.
