New Light & Darkness Demo?

The demo version of a "confirmed" Christina Aguilera track 'Darkness into Light' has apparently leaked from her up-and-coming album, Light & Darkness / ShadowLights (rumor).

This was confirmed today by an associate of Sia Furler, via Twitter, and then leaked today by the same account. This original demo is believed to be produced and written by Sia, herself.

The album is slated for a 2010 release date (Confirmed October 1st, 2009 by Tricky Stewart in an interview with Rapup TV).

Enjoy. More Xtina News Coming Soon!

Thanks to brizz for the heads up!
