For example, "My Heart Will Go On" is from the movie "Titanic", "Still Alive" is from the game "Portal" and "Gotta Catch Em All" is from the anime "Pokémon". Obviously there are still artists/composers behind the songs, so listing "Titanic" as 'artist' feels wrong.
Is there a common term that can be used to describe what these songs are famous for, that can be used in a simple format like
XXX: Titanic and works not only for movies, but also for games, animes, etc.?
