Also, Georgian Polyphony did not involve strings as a general rule. There were regional exceptions, but early Slavic polyphony was generally a capella.
Spotify, and other commercial online sources, have long failed to get genres like "classical" right. It sounds like they're screwing up "Byzantine" as well, which is sadly unsurprising.
I've noticed miscategorizations in other genres as well.
But It's OK. I think the interesting thing is how the musical snippets are different from each other rather than whether or not they're correct in an absolute sense.
It's a step in the right direction, I think. And it's not surprising that the categorizations and recommendations you get on music streaming services like spotify aren't as ridiculously off the mark as they used to be.
It seems like "Byzantine" is just an unfortunate label, which should be "church music", but if you expand it you will see that byzantine chant is present.
It's still too broad. Byzantine chant is an entire discipline in itself, and so are a bunch of other categories included in "Church Music". There's a category for Anglican choirs, so why not for Russian "Greek" chant or Kievan/Znamenny Polyphony? There's a lot of territory here.
The way this concept would really work, in practice, at a streaming service is as the basis for some kind of cluster analysis that could predict what you might want based on your listening behavior and that of others "like you".
Having people use words to precisely pin-down entire genre's is perhaps near the end of it's usefulness.

Here's a good example of Gerogian polyphony: https://v-s.mobi/elia-lrdei-princeton-georgian-choirs-fall-2...
Sorry to nitpick, but I hate to see a fascinating corner of music ignored. Happy Listening!
