Shazam produces an embarrassing number of false matches, which I assume are hash collisions or something similar in the world of their fingerprinting system?

Near enough is good enough for most people paying-for/selling the tech.

Shazams correct hit rate has certainly lowered in the many years I've been using it. Presumably because the pool of music it now is being asked to decipher is becoming unwieldy.

I am permanently pleased to learn one size does not fit all even in gargantuan saas companies.
