It's really fun to watch this with element inspector dev tools open on a second screen and watch the element attributes change in sync with the music. It reminds me of someone programming electronic music on the really primitive DOS synthesizer/MIDI programs.
That being said, the fact that there's an NFT associated with this is extremely stupid. Aside from that this is perfect.
Edit: for a fun bonus, watch the elements inspector try to keep up with the updates inside main > #container.
