John Lennon's Imagine has always resounded with me. I never understood why certain songs had that effect on me a deep and touching way, but over time it made more sense.
There's a reason why he's a visionary. His idea might not make sense in the present world in a cursory view, but when the world's evils go away, think about what we can achieve.
I will just say that every line has relevance and meaning, it is encoded in a way that might not make sense now, but we'll look back and realise he really was sent from above.
