Does it really matter now? The album was released back in December 2010 - more than seven months ago. Sony has no intention to push the album any further. I guess they will focus on the Cirque show soon.
Anyway, I fail to feel any excitement of single release at all. All we got were very average videos (although I do appreciate fans' efforts in BTM) and some official remixes.
In this day and age, record company no longer releases CD single unless the single is a blockbuster hit. And now, we know there will no longer be any new performance by Michael.
Radio stations mostly play Katy Perry and Lady Gaga.
