Wow, this is super fun, and a great sampler of a wide variety of music!

I was curious about the composition of music, therefore a friend and I created/curated frequency-domain visualizations of a variety of music in different languages and interesting sounds using the Welch power spectral density estimation algorithm and Fast Fourier Transform. The visualizations are fun to look at and with some practice you can distinguish the different instruments and vocal tracks in each song.

The 56k modem was so cool
Thanks, glad that you liked it!

The Megatronix SC620 Six Tone Car Alarm is also fun to watch: https://www.youtube.com/watch?v=xXYc0gtOswQ&list=PLn67ccdhCs...

As well as the a cappella Starships (Nicki Minaj cover) by Mike Tompkins which has a mind-blowing breakdown of how he built up the composition from different vocals at the end: https://youtu.be/vDqHpWY1UD4?t=209
