First she saved Bionic for Christina Aguilera (in the sense that her contributions were amazing, not in the Billboard charts way), then she delivered big time for Guetta and Flo-Rida with her presence on “Titanium” and “Wild Ones” this past year, now she’s at it again but this time for Leona Lewis!

Sia continues to prove what a force she can be for POP music with “Blank Page”, a tune penned for the upcoming Leona Lewis project Glass Heart – which btw, what the hell happened with Glass Heart being released in March? I hear it’s now due for a November 2012 release… ridiculous!

Listen to 30 seconds of the stunning ballad “Blank Page” as sung by Sia below, it’s simply gorgeous. A release soon would be nice Leona/Sony!

What do you think of the tune?
