The process of chipping away at a list of 500 songs must be incredibly daunting, but it definitely means that there's no shortage of music to accompany a dramatic (or hilarious) Guardians scene. It's important to remember that the soundtracks for the first two Guardians of the Galaxy movies cannot include any music made after the death of Meredith Quill. James Gunn specifically looks for songs that Star-Lord's mother would actually listen to, and he then tries to find ways to weave them into the story beats of a given film in a way that makes sense. Whether it's "Hooked on a Feeling" for a triumphant escape, or "Father and Son" for Yondu's funeral; it all serves a purpose.
