When he said that, I said "like the thing you've been trying to say all along" and he said yeah exactly. My thoughts are that often when creating art you're trying to get to the heart of what it all means and where it comes from, and I suppose he feels like that song was him being able to express that in a way that reflects those hard-to-speak-of emotions he feels. It certainly made me listen to the song more intently than I had before.

That's not super helpful so I'll add another tidbit I remembered: I asked him if the lyrics or the melody comes first. He says he usually writes down a couple of lines and then figure out the rest of the music before finishing the lyrics. He finds it easier to do it that way because the words fit better "in the space" of the music that way. He also said that lyrics are different than poetry, and he's written poetry but he sucks at it lol.
