A Zune is a real-world object in the Marvel Cinematic Universe. It is a portable media player.
After the death of Yondu Udonta, his first officer, Kraglin Obfonteri, gave it to Peter Quill (Star-Lord) as a gift on behalf of the late Udonta, something that he considered using to bribe him back into the Ravagers. Although Kraglin and Quill are impressed that it can hold three-hundred songs, it was actually a discontinued product in 2011, with Quill receiving it in 2014. The bigger joke is that the film is actually a 2017 production.
- It appears in a deleted scene in Avengers: Infinity War (2018).
