Do you normally expect that free as in beer apps are going to be accurate to the degree that a data harvester with years of experience and funding?

I've never used Shazam but did use the music recognition app on pixels when I was the stock ROM. Audile seems that it gets about 80% of what the Google app would get. I'd imagine that would change depending on the kind of music you're often trying to identify though, Audile is probably working with a smaller database of some genres.
