It's one of my favourites from the album and with it being a ballad it is probably their best chance of success considering 'Say Something' and 'Gravity' seemed to be their two most popular X Factor performances!

 

 

Amazing! It really should be a worldwide hit. :(

Wow.

 

That is seriously incredible. It will flop worldwide but it really should smash. I hope they promote

This as a lead single in the UK because it is seriously stunning.
