There’s no denying that a major part of “Guardians of the Galaxy’s” charm was the movie’s soundtrack, which managed to seamlessly blend action with an eclectic track list. Luckily, the film’s follow-up, “Guardians of the Galaxy Vol. 2,” will place an even bigger emphasis on the sci-fi superhero sequel’s tunes.

According to ScreenRant, the soundtrack for the second film was chosen by director James Gunn during the scripting process. The selected track list looks to be pulling from an even more famous batch of songs, including the like of Sweet’s “Fox on the Run,” which played over the film’s teaser trailer. Marvel Studios president Kevin Feige broke down the selection process and how music is perceived by the film’s characters, saying,

[The Music] is all off the tape. It’s all off of Volume 2. I would say that the other Guardians now know that music is a thing for Peter, so in early scenes, what you see baby Groot here, which he’s just ‘Groot’ in the movie, but on set we call him baby Groot, he’s setting up these little outer space speakers so that the music can play for all of them, because Quill likes to hear music when he’s fighting. So, it does go to more than just his headset, but it’s all based off of Volume 2. And I would say that a couple of the songs, and particularly one song has very unique lyrics that play in much more specific part into the plot, than any song did in the first film.

Song licensing for big Hollywood movies is notoriously pricey, though. If something on a track list rings up too many dollar signs, there’s always a chance the director will have to find a replacement. Fortunately, Feige said Gunn’s first choices made it into the movie.

We’ve cleared all the songs that were in the script, yeah, yeah. You don’t actually pay for them until you cut the movie together and decide. If you use the first movie as a track record, every song, maybe one or two songs came out of the movie that were, that had been in the script, for length more than anything else, but we’ll probably end up using the vast majority of them, and certainly the ones that play into the plot and dialogue are in.

Debuting in theaters on May 5, “Guardians of the Galaxy Vol. 2” is directed by James Gunn and stars Chris Pratt, Zoe Saldana, Dave Bautista, Vin Diesel, Bradley Cooper, Michael Rooker and Karen Gillan.
