My understanding is that song fingerprints are tiny, so it's not too prohibitive to store an entire catalog of them on the device.

That's weird, because the AcoustID database is over 160GB: https://acoustid.org/database

Then again, it does have 48M fingerprints, so that's only ~3.3KB/fingerprint. Maybe Google has a decent subset in a reasonably-sized package.

Reports on the Pixel library have it at either the 10k or 20k most popular tracks only. That makes for a reasonably small library.

at 3.3kb it's only about 64mb to store 20,000 songs. If they periodically update that (in the background, on wifi, etc) you'd likely never know. It's basically noise when OS updates are multi-gb.
