By August 2014, Gunn had "some ideas listed, but nothing for sure" in terms of songs to include in Quill's Awesome Mix Vol. 2 mixtape.[71] In April 2015, Gunn said he felt "a little pressure for the soundtrack because so many people loved [the first film's soundtrack] and we went platinum and all that other stuff. But I feel like the soundtrack in the second one is better."[113] In June 2015, Gunn stated that all of the songs for Awesome Mix Vol. 2 had been chosen and built into the script.[5] Gunn had hoped to include "She's Gone" by Hall & Oates in the film, calling it "one of the greatest pop songs ever written", but could not find a place for it.[114] In January 2016, Gunn stated that he had chosen an additional Bowie song to appear in the film (after "Moonage Daydream" was featured in the first film) but had cut the original scene it was featured in. The inclusion would have made Bowie the only artist to be featured on both mixtapes. With his death however, Gunn hoped to find a way to include the chosen song somewhere else in the film as a "fair and appropriate" way to honor him, as Bowie was one of Gunn's idols.[96] Gunn called the Awesome Mix Vol. 2 "more diverse" than the first one, with "some really incredibly famous songs and then some songs that people have never heard."[115] Sweet's "Fox on the Run",[116] George Harrison's "My Sweet Lord", Fleetwood Mac's "The Chain", Jay and the Americans' "Come a Little Bit Closer",[117] Bowie's "Suffragette City",[118] and Parliament's "Flash Light",[119] are some of the songs Gunn is considering for inclusion on the Awesome Mix Vol. 2.[120]
Tyler Bates had returned to score the film by August 2015.[121] As with Guardians of the Galaxy, Bates wrote some of the score first so that Gunn could film to the music, as opposed to Bates scoring to the film.[93] Recording for the score began in January 2017 at Abbey Road Studios.[122]
