first post here! I'm kind of a noob in JS but I'm working to improve. So, I'm building [this](https://roy-05.github.io/audio-visualizer) audio visualizer using vanilla JS. I still need to work on the CSS but I'm satisfied with it right now - It can decently visualize FFT data for a preloaded song (taken from Free Music Archive)

I now want to **connect a streaming service like *Spotify* to the visualizer so that the music from the streaming service is visualized**. But I'm not exactly sure how to go about doing that. I'm using the Web Audio API to analyze the sound. 

I would really appreciate it if someone could provide some direction in going about this, thank you!
