Awesome Mix Vol. 2 contains songs featured in Guardians of the Galaxy Vol. 2.
Following the death of David Bowie on January 10, 2016, James Gunn stated that he wished to include a Bowie song on the soundtrack, making him the only artist to be featured on the soundtracks of both films.[1]
Footage shown at the 2016 San Diego Comic-Con International featured the songs "Come a Little Bit Closer" by Jay and the Americans and "The Chain" by Fleetwood Mac, though Gunn would not confirm whether or not they would be on the soundtrack.[2]
