Elvis Costello - " Travis McCoy - "Sugar We're Going Down"
Gabe Saporta - "Grand Theft Autumn"

Brendon Urie - "Dance, Dance"
Doug Neuman - "This Ain't A Scene, It's An Arms Race"
Alex Deleon - "Thnks Fr Th Mmrs"

Stump explained to AbsolutePunk why this is probably his favorite song on Folie a Deux. "It's a really interesting thing where Pete was kind of writing in a character, and the weird thing is that it's like me, it's as if I wrote the lyrics,
but I didn't. And I'm not being narcissistic, it's really cool,
like it's impressive to me how well he has me figured out,
so it just made me respect him that much more as a writer.
It's weird, it felt like I sat down and wrote a confessional song,
but I didn't. It feels like that to me, but I didn't.
I was writing off of Pete's lyrics, but it's as if I was confessing through them."
