Hello all, I have this idea of using the title from a Prince's song as the title for my novel. I have other options but *that* title would fit just perfect (Darling Nikki). The song is mentioned in the story and the main female character is called Nikki. What problems do you think I might have if I use the title? Who should I ask permission to? Record label? I know it's gonna be hard to obtain it, but I want to try at least before opting for a different title.
