Ok, so my question for you guys is can I use names of songs and other works as the chapter titles? In specifically, I wanted to use “Jar of Hearts” as a title for one chapter, because I love the song, and it fits well with my theme, and then I wanted to used “Fall of the house of Usher” as another chapter title, because one of my characters last names is Usher, and it would fit well with the evens in that chapter while paying homage to another literary work I love. Like, I know I can’t use “Harry Potter and the Half-Blood Prince” for a chapter name, and I can’t see why anyone would want to either….. But anyways, I just wanted to ask because I didn’t know if it would be acceptable, or frowned upon. Thanks for your help!
