^Who is this even? - _ -
Anyways, I think it was their strongest performance outside "Impossible." Hopefully they'll be on the right track next week. A part of Samantha Jade winning X-Factor Australia this past season was her and Guy's ability to give the other judges what they want and still be innovative. The "Heartless" performance turned everything around. They need to harmonize more but figure out how to do it in a unique or incredible way.
Good luck next week!
