Well, the bleeding and dying is a bit depressing, especially since in the song blue = happiness.
I've never heard anything about those lyrics, either, the green thing I heard back when it came out and I think my dad said he heard it too (I trust his word, considering he's a DJ and his life revolves around music and weird facts).
But, no matter what it originally was supposed to say, it now is just that gibberish, as the song title states.
I found this while searching...
And...
So, if that's true, then the whole bit about happiness was bullocks and it was really about sadness and suicide.
I don't know much about the suicide of the lead singer and this is all news to me, but just thought it was interesting.
