I have faith in Vanessa. If she thinks White Houses will be a good first single, then it will be.
It doesn't matter what she thinks when it comes to a single (it does for her music, but like Rosie said Commercial Success is a must if she wants to continue in the music bus.).
All that matters is, 1) Radio stations like it 2) the people like it and 3) it sells...
It may be sad, but that is how it works.
