Fantastic idea and implementation! Just FYI, it seems that in the music community, there are quite some complaints about how Spotify distributes the income for artists. I don't know the details so no further comments from me. But I think it would be great if this project can be abstracted into an indie Web Audio visualisation lib. I would be keen to try it with my project Glicol:

There I have only basic visualisation so far.

Earlier quoted context omitted.

Back then I could run a music visualizer offline. I have no idea why this website requires me to log in to Spotify.

It doesn't sync to live audio it records/grabs. It uses the Spotify API that provides rythmn/intensity mappings for most (all?) songs. So basically the web page asks the API which song you're currently playing on Spotify and what BPM it has and it renders the visualization accordingly.

Also:

It currently seems to use Spotify's audio analysis API [1], which might be hard to replace.
