Unlike the semifinals, the singing hopefuls now only have two ways to pull themselves to number one: winning the public vote or boosting their votes with the iTunes Top 10 multiplier. Recently, everyone and their brother has managed to snag the iTunes bonus, which means this talented field may need to rely solely on viewers' voting power if they want to walk away winner.

Team Adam Levin's Jordan Smith took the stage first. Generally considered the leader of the 2015 pack, Smith choose to Climb Ev'ry Mountain as his solo performance before diving into a duet of God Only Knows with Coach Adam. For his Christmas song, Smith took on the lesser-known Mary, Did You Know.
