Not sure. I found both those covers by searching it on Spotify. It's like my dad's favourite song. Probably some combination of school shootings, hopelessness, irony.
It's the Kid A part that's nostalgia though. That's some "let's get belligerently high in a cubbyhole next to a school and borderline hallucinate we're in Battlestar Galactica after jacking the angular momentum of Grandma's garbage can."
