I love how the Theme of King J.J. went from narcissistic anthem to deeply inspirational real quick. Go listen to the lyrics again! It’s so clever how the meaning of the song changes with the context of the scene.
The first time we heard the song, the lyrics suggest that he is an overbearing, pompous ass who thinks he’s top shit - we can infer this from the way he excudes so much confidence. But after his breakdown, it’s like the song is symbolic of his uphill climb to get to where he is now. It shows his tenacity and incredible fighting spirit. I fucking love that.
