XOX sings 'Problem' on The X Factor Australia 2014 (VIDEO)

XOX sang 'Problem' on The X Factor Australia 2014 Live Show 4.

This should have been amazing, and I'm struggling to think of why it wasn't. The individual vocals were off, the harmonies were barely noticeable, and the only thing that really worked for me was Serenity's rapping. And, I suppose, the choreography and overall energy of the performance, as these girls have serious stage presence. But it was hard to ignore how messy this was, musically. I wanted to absolutely love this, but I just felt like it didn't work the way it should have. I didn't get the praise for this at all.

But what do you think of XOX?
