Marvel's Guardians of the Galaxy became one of the rare instances when a soundtrack extended beyond mere background music, with the "Awesome Mix" resonating in its ability to drive home the film's tone and sensibilities. Director James Gunn's sequel further accentuated the importance of music, with "Brandy (You're a Fine Girl)" by Looking Glass playing directly into Vol. 2's plotline and backstory for its lead character, Star Lord (Chris Pratt), and his father, Ego (Kurt Russell).RELATED: James Gunn May Have Just Teased Quasar for GOTG3With pre-production under way for a third film, one fan of the beloved Marvel Studios franchsie reached out to the director to ask about the status of the soundtrack. The filmmaker's reply demonstrates it's a time-consuming process assembling songs that work so cohesively within the narrative.

Because most motion picture soundtracks range from anywhere between 10 and 20 tracks, Gunn still has a ways to go, especially given how much music he has to pull from the massive pool of classic '70s and '80s that has been the source for the first two films. However long it takes the director to finalize the list, it will undoubtedly be worth the wait, particularly given the fact that Vol. 3 looks to be the last time Gunn will helm an adventure featuring Star-Lord and company.
