"I" by Black Sabbath. Because it's all about the power of one: "I am anger," a rebel, a holy outlaw. Favorite line, "all together, you'll never be stronger than me."
"Starless" by Crossfade. About falling to the darker side:
"I can transcend you and mentally bend you
But I can't handle the [!@#@] that I'm into
I have been blinded I'm always reminded
Of the things I've wanted but I never could find."
"Shadow on the Sun" by Audioslave. Another epic song.
"i could read your thoughts
and tell you what you saw
and never say a word
but now all that is gone
over with and done
and never to return"
