With Hamilton, it's subtitled "Book, Music, and Lyrics by Lin-Manuel Miranda". However, with The Last Five Years, it's "Written and Composed by Jason Robert Brown". Is there a difference between these two terms? Or is it up to the author to choose his title?"
It all depends on how pretentious the writer wishes to be. In the case of JRB, the answer is VERY!
