Wow, that's fascinating! I just ended up down the rabbit hole reading Avery Wang's "An Industrial-Strength Audio Search Algorithm" (linked in this thread) - it's such a cool way of "fingerprinting" pieces of music data.

My original comment was from memory of reading a post about how it worked a few years ago. Looking at what you read, I think the gist of what said is right, though it seems they use a different algorithm than FFT.
Totally agree though. It is something that opened my mind to thinking of a way to solve that problem in a way that actually works. Shazam definitely looked like magic the first time I saw it work.
