I’m wondering the intention of the “Songs” credit on this site. Is it designed to lists the artists who have songs in the movie (example: Hunger Games: Catching Fire https://www.themoviedb.org/movie/101299-the-hunger-games-catching-fire/edit?active_nav_item=crew , which is not a musical and these are just soundtrack credits) or is it designed for something like Rocky Horror Picture Show, which is a musical and has songs that the characters sing? I’m not sure if there’s really a difference here.

My main question is, should I be adding a “Songs” credit to everyone listed on the soundtrack portion of the credits?
