Canada:
#5 - Do What U Want (+1)
BAM!

At least it's doing pretty well somewhere...
Anyways, this is
WHAT I WAS TALKING ABOUT. All she needed after The Voice performance was to enter the Top 10. That would have granted her extra exposure and the song could have had a fair chance to stabilize in the Top 10 and give us some really great holiday sales. Seeing how in the US the Top 10 wasn't achievable even with big promo, she should have released the music video right after. That could have definitely pushed the song into the Top 10 and possibly ignite the general's public attention in it.
Just look at Canada, her performance on The Voice pushed the song from #12 to #5 on that day. One week later, she's still top 5 and constantly increasing in sales. It has all to do with the exposure of the song. I really think the US public isn't yet familiar with the song, both because it's a feature with R. Kelly and also because it's a total different genre from Gaga's usual dance-electro driven songs.
I still think it has some potential left in it, if threaten with an amazing music video in the near future..
