I mean, is anyone really surprised about it dropping? The label needs to somehow get people interested in Vanessa again, NF didn't really manage to achieve that, so no one can expect NF to stay on the charts with us being the only small group really supporting it.
We can only do so much. :?
We need to see her in other mediums, like a fashion spread in Vogue or something if possible. Things that'll grab people's attention. In order to be successful you can't just be solely focused on either acting, or music. You constantly see entertainers and celebrities delving into other mediums - fashion, fragrances, jewlery, etc.
Edit - I could definately see Vanessa doing some occasional freelance acting, especially in a black comedy for some reason. She has the demeanor that'd be perfect for that from what I can see.
