The only true immortality is when you don't care if you die. The moment you stop giving credence to gain is when you become invulnerable to pain.
Let's face it songs are about love, which is, I love you, I don't love you, come here, go away, I miss you, I don't miss you. I'm lonely. I'm not lonely. It's, it's all about affairs of the heart. And we can all relate to those.
