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.
