Two of Jennifer's artists are handed the tall order of taking on a beloved Whitney Houston #1 song. Blake and Rascal Flatts are impressed by Blake's left of center rock artists, whose electrifying performance of a 90's alt rock hit puts Blake in an agonizing position and the other coaches on notice. Adam and Joe Jonas task two of Adam's powerhouse vocalists to put their own spin on a current chart-topping pop song, and their emotional delivery leaves the coaches floored. Blake, Jennifer, and Miley each have one steal left. Adam has two, and is on the hunt.
