What is the most powerful, perfect song you’ve ever heard and why?

What is the most powerful song you know. That 1 song you think is just absolutely perfect. I know I have quite a few, but there's 1 that tops em all. But before I let you all know mine, I want to hear yours.

And coming in closely at my #2, is by Faster Pussycat, house of pain. I don't know about it being beautifully played out... but it's perfect to me. And explains almost exactly who I am. I think that's why I love it so much
