siaSo we all know Christina Aguilera’s newest album hasn’t done so well… but how about when a demo version of one of your tracks is way better than the released and sung by another artist?! Yeah that happened. “Blank Page” one of the tracks off Xtina’s Lotus album was originally recorded by Sia.

Here is the Sia version and the Christina version… Which do you think is better?

Sia – “Blank Page”

Christina Aguilera – “Blank Page”
