Guardians of the Galaxy is the film score for the Marvel Studios film, Guardians of the Galaxy. Composed by Tyler Bates, the score was released by Hollywood Records on July 29, 2014. A separate soundtrack album titled Guardians of the Galaxy: Awesome Mix Vol. 1 (Original Motion Picture Soundtrack) featuring the songs and artists seen on Peter Quill's mixtape in the film, was also released on the same date, along with a deluxe version featuring both albums.
In August 2013, Gunn posted on his Facebook page that Tyler Bates would be composing the film's score. Gunn stated that Bates will write some of the score first so that he can film to the music, as opposed to scoring to the film. In February 2014, Gunn revealed that the film would incorporate songs from the 1970s and 1980s, such as "Hooked on a Feeling", on a mixtape in Quill's Walkman, which acts as a way for him to stay connected to the Earth, home and family he lost.
In May 2014, Gunn added that using the songs from the 70s and 80s were "cultural reference points", saying, "It's striking the balance throughout the whole movie, through something that is very unique, but also something that is easily accessible to people at the same time. The music and the Earth stuff is one of those touchstones that we have to remind us that, yeah, [Quill] is a real person from planet Earth who's just like you and me. Except that he's in this big outer space adventure."
