I listen to Muse enough, that even in VRC6 8-bit form I can hear the lyrics by ear. I love listening to 8-bit/16-bit/SID/Chiptune covers of songs so it comes natural~
Good luck getting THAT out of your head.
I was going to put the Talking Heads one, but then I got thinking of opera cause they tend to have some kind of tragedy theme, and then this happened.
For the literal and figurative "killer", this song comes to mind. Not all killers are murders~
I can't look because it's killing me.
