Although "Guardians of the Galaxy Vol. 2" doesn't cruise into theaters until May 5, the long wait is over for what songs appear on the sequel's soundtrack. Marvel has unveiled the "set list" for the "Awesome Mix Vol. 2," which goes on sale Friday.

Sweet's 1974 single "Fox on the Run," featured prominently in the trailers and TV spots is there, of course (although it apparently doesn't appear in the film), joined by such fellow '70s gems as Electric Light Orchestra's "Mr. Blue Sky," Fleetwood Mac's "The Chain" and George Harrison's "My Sweet Lord."

However, at least one track will be unfamiliar to even those most devoted fans of '70s rock: "Guardians Inferno," by The Sneepers featuring David Hasselhoff. That's because it's a comedic original written by director James Gunn and score composer Tyler Bates. According to Rolling Stone, which spoke with the filmmaker about the soundtrack, it's "meant as a sort of 'Guardians' take on Meco's disco 'Star Wars' theme." And Hasselhoff? He's one of Peter Quill's childhood heroes, naturally.

Gunn noted that along with crowd-pleasing classics, "Awesome Mix Vol. 2" includes its share of obscure songs, like Silver's "Wham Bam Shang-A-Lang." "One of the most exciting things was knowing I would be making bands that may have been forgotten suddenly be a topic of conversation," he told Rolling Stone.

"Guardians of the Galaxy: Awesome Mix, Vol. 2" is available for digital download beginning Friday.

Written and directed by James Gunn, “Guardians of the Galaxy Vol. 2” stars Chris Pratt as Star-Lord, Zoe Saldana as Gamora, Dave Bautista as Drax the Destroyer, Vin Diesel as Baby Groot, Bradley Cooper as Rocket Raccoon, Michael Rooker as Yondu Udonta, Karen Gillan as Nebula, Pom Klementieff as Mantis, Elizabeth Debicki as Ayesha, Chris Sullivan as Taserface, Sean Gunn as Kraglin, Glenn Close as Irani Rael and Kurt Russell as Ego.
