Does it seem weird to anyone else that marching bands commonly play "Paint It Black" at sporting events? Isn't that song, which seems to be about consuming depression following the death of a lover, at an odd juxtaposition with "The Hey Song"*?
"I look inside myself and see my heart is black"
Ummmm, Go Team?!
"No colors anymore I want them to turn black"
I guess you could argue the same about "The Imperial March" (aka, Darth Vader's theme), but that at least has an ominous, threatening vibe you might want to instill in your opponent. "Paint It Black" isn't threatening, though, so unless your goal is to really bum the other side out I don't get it. Seems like when you're trying to rally a crowd, a song commonly used as the backdrop to Vietnam War movies shouldn't be your first choice.
*Fun fact: Some part of your mind is always listening to "The Hey Song," over and over.
