Song One Puzzle

There once was a song which acknowledged itself in the words
It was like when your parents heard The Beatles
Ripped the wind from our lungs and left us defeated
It made me and Duncan embrace when the awesome guitars swell
And the bass cuts out so it's just the voice and the riff

There once was a song which dismantled itself in the words
It set sail, while in Shea Stadium they shouted:
"We collected the fragments as they radiated outwards"
The guitars fell from their hands as chords decomposed
And champagne explodes on the bows
Of a song that shifts from blows into hits
