I've never really listened to either of them, but some phony list of my favorite music circulated on social media, [REDACTED]. Rather than being a buzzkill and set the record straight, I figured I'd see what all the hype was about. So I'm walking laps on the top tier of my unit listening to 'Cardigan' by Taylor Swift when one of the other inmates, 'King,' calls me over to see what I'm listening to. He scolds me for a while, then replaces all my music. Now I listen to 'Lil Durk.'"Netizens reacted to Mangione's revelation, saying:"A man with culture and taste"joey 🍿 @turquoisepogosLINKA man with culture and tasteNetizens' reactions to Luigi Mangione's prison letter revealing he's been listening to Taylor Swift and Charli XCXPop Base took to its official X (formerly Twitter) page to post that,"In a letter verified by TMZ, Luigi Mangione reveals he has been listening to Taylor Swift and Charli xcx in prison."Netizens were notably quick to weigh in on the comment section of the X post as they penned their opinions on the matter.

If anyone was hit by that it’s me. @MangioneTrial was more excited about me getting to know about this than receiving the letter herself. One of the things I have added into my 20 something things I’m grateful for was Taylor, and he did the same. Also, the way he gives Taylor a “nickname” by calling her “T Swift” 😭", expressed another."Now this is just engagement and marketing farming, no shade to the artists though", commented a third.Notably, Luigi Mangione's behavior in prison has also become a topic of conversation.
