Now morally, I don't agree with the killing, but musically... I can understand the use of "Helter Skelter." It's loud and it's scary and it's boogeyman-ish.
But if you think about it... that song was only a year old when the murders took place.
I dunno. Seems kind of rushed, y'know? Or too late? Lame, in any case.
It'd be like if I murdered people and wrote "Hey Ya!" on the walls in blood.
And it'd be in January. And I'd be wearing a Santa hat.
