Alex and Sierra appeared on and won the last season of 'X Factor' here in the U.S.

They instantly stole the judge's and America's hearts with their couple love and quirky arrangements.

They have finally released their debut single, 'Scarecrow.' I personally really like the song.

It is kind of like The Lumineers 'Ho Hey' had a baby with Phillip Phillips and Mumford and Sons.

American X Factor winners haven't had much success in America. Maybe Alex and Sierra can break that streak.
