That’s a really cool list of stuff!
(This isn’t very “discovery” focused, but reminded me of rooms.xyz: https://www.cyberdoof.com/ – found this via Golden Shrimp Guild’s “SynthOn” Twitch event, the person who coded it got involved. Found it really fun to hang out in).
I’d be interested to be a part of this. I think algorithmic recommendation systems tend to completely hide weird music like mine. A discovery method based on real communities, & shared aesthetics sounds good to me!
