Star Spangled Man with a Plan
With Bucky, the only time you sing around him is when you're singing quietly along with the music you're listening to and Bucky loves it.
Everybody Wants To Rule the World - Tears for Fears
Flash - Queen (It may not be about The Flash, but it still mentions the name, which bugs him)
Robin Hood: Men in Tights
U Can't Touch This - MC Hammer
Iron Man - Black Sabbath (He wishes you would take it more seriously)
Literally anything, that's not sung seriously
Witchy Woman - The Eagles
