Spoilers for "Deadpool & Wolverine" follow.

The soundtrack to Shawn Levy's new superhero flick "Deadpool & Wolverine," the 158th film in the Marvel Cinematic Universe, is chock-full of sarcastic needle drops and overblown musical cues, wielded specifically to amp up the movie's irony. "Deadpool & Wolverine" opens with a violent fight scene wherein Deadpool (Ryan Reynolds) murders dozens of people using the adamantium bones of the deceased Logan as weapons. On the soundtrack, *Nsync's "Bye Bye Bye" plays, adding a silly, upbeat quality to the violence. 

Later in the film, Deadpool and Wolverine (Hugh Jackman) will get into a knock-down, stab-happy fight in a Honda minivan, spraying their own blood all over the car's interior. As they fight, one of them smacks the radio, and "You're the One That I Want" from "Grease" plays on the soundtrack. It's a jaunty, happy tune that serves as a comedic tonal juxtaposition to the slicing and dicing.
