My quick answer is
Born To Kill by Matthew Good Band, but really that's just because I found the song during that enormously impressionable time between 16-18. I imprinted on it like a duckling.
My deeper answer is 10,000 Days by Tool, mainly for the story behind it.
Judith is a song by the lead singer's other band A Perfect Circle, which is an angsty middle finger to his mother for believing in a God who would leave her paralyzed following a stroke.
10,000 Days comes 6 years later, after Judith has finally died after 27 years of paralysis (about 10,000 days) and Maynard James Keenan has come to terms with her unwavering faith. He still doesn't believe, but there's an acceptance there and an expectation that if God should exist, he'd better treat him mom with some respect that she's earned.
When people talk about AI doing creative things like painting or music, I feel we're probably not far off from a time when humans can't tell the difference. This is one example where I can't see a machine being able to match. The song is good because the song is good, but moreso because it has a 27 year story behind it, and that makes it matter on a human level.
