Probably best. I feel like with the right music (the 2014 Back to Basics, essentially), since she looks better than ever and has her voice where it should be, she could really make a decent comeback.
I can't wait to see what she comes up with. Especially after she was inspired by Say Something and after she said that there was a possibility she would work with Ed Sheeran
An album like Paloma Faith's Fall To Grace could be a success for her !
Something modern yet soulful but not a second B2B cause that will bore people I think...
I mean, I want to hear her voice on big songs with strings and synths, I think it'd really fit her voice if she doesn't belt all the time though !
