These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Big Lipped Alligator Moment: The "Rock and Roll Girlfriend" bit of Homecoming doesn't make sense in the album's context, and was never mentioned before or after the song. It makes more sense when you realize it's about Tre's life, but it still doesn't really fit in with the rest of the album.
The very beginning of "Extraordinary Girl."
For a few years after its release, several older and more hardcore fans tried to play the entire album off as a BLAM within the band's career.
"Wake Me Up When September Ends" doesn't really fit with the album's overall narrative. The song was written about the death of Billie Joe Armstrong's father.
In the musical it gets a little more explicit - while JOS and Whatsername serenade each other, Jimmy leans mournfully over the balcony and sings to JOS,
I text a postcard, sent to you
Did it go through?
Sending all my love to you.
You are the moonlight of my life every night
Giving all my love to you
It could likely be interpreted as JOS' thoughts/feelings about Whatsername at the time, considering the Double Consciousness interpretation.
Suspiciously Similar Song: "Boulevard of Broken Dreams" is uncomfortably close to Oasis' most famous hit "Wonderwall". At least one mashup between the two exists, and Noel Gallagher complained, saying he at least plagiarizes from dead peoplenote Which must come as news to Stevie Wonder who got a co-writing credit added to an Oasis B-side for obvious plagiarism.
"II. City of the Damned" also sounds a lot like "Summer of 69" by Bryan Adams.
And "V. Tales of Another Broken Home" sounds a lot like "Ring of Fire" by Johnny Cash.
