I really enjoyed working at Shazam. One of my favourite parts were the hackdays, got to learn a lot. Here's a write up of visualising music recognitions: https://medium.freecodecamp.org/data-visualisation-with-1-bi...

I've been planning to do more write-ups from past hackdays, such as building a functional Shazam experience in client side JavaScript and other visualisations. For example one time, I repurposed a WebGL globe to plot music recognitions over it. I don't have access to the Shazam tag stream anymore, but you can get a feel for how this looked as I've applied near real-time Wikipedia edits on the globe instead: https://umaar.com/globe/
