The verses use baby's first whole tone stepwise rising chord progression, which does serve the musical idea of building momentum but it's really fucking boring on its own. They took that musical white bread and did the absolute simplest thing you can do to avoid boring the listener - adding a little chromatic embellishment in the melody right at the end of each measure. Bare minimum, but it gets the job done with no fancy frills. The pre-chorus sections do a good job of hyping up the chorus too, with upward modulation to build intensity and some pronounced left/right panning all to put even more emphasis on the main idea of momentum. My favorite part is chorus where they did a cheeky swerve on the full Royal Road (IV-V-iii-vi-ii-V-I) progression -
seriously the nips put it in everything - doing the onramp meme at the ii chord and using it as a pivot point, first to set up a second lap of IV-V-iii-vi-ii and then as a springboard for the next key change. I haven't sat down to try and transcribe it all because that's youtuber behavior, but there's a lot of solid fundamental understanding of music in there. It's not revolutionary, but I still enjoyed it as sugary musical junk food. It jingles the keys just right, the mixing seems good and I appreciate that they recorded lots of different vocals to account for which characters are present in the scene.
