Give it time. Sometimes the simplest move is right.
Yes, I know, what I was trying to say is that the BTW Ball in the US wasn't sold out until a few weeks or days before of the concerts but at the end it end up sold-out
I assume Monday or Tuesdays would be the best days, right? The video gets a full week of streaming.
Then she should wait until she has the full week of streaming + by that time she should be 11 or in the top 10 on radio + hopefully remaining steady on itunes + the video will give it a boost on itunes
