Thanks for the feedback! This being Angular 2 we actually used TypeScript, with some Django on the backend (with some Node.js and Ruby for generating the waveform data using ImageMagick).
We also used Three.js for the 3D visualizations -- the sphere one is especially cool. Put on on some music and check it out by clicking the menu and then the circle icon on the top left.
We also have some cool 2D visualizations in the equalizer (click the arrow on the left of the player to access).
All in all this was a very fun stack to develop on, once we had all the initial pieces in place (getting ngrx/store set up mostly) we added new features very quickly. We got to where we are right now over the course of less than 3 weeks.
This is all hosted on a tiny DigitalOcean droplet and we use external APIs with daily limits, so hoping it all stays up while it's on the front page here!
