I will! Actually I started a personal project for music discovery and exploration. It's currently a dirt simple local app with about 50k tracks (YouTube embed, track credits, genre, rating).
I was going to add Spotify metadata from that recent data dump, but it's kinda trash data (valence isn't trustworthy, wildly wrong a lot of the time).
I then stumbled on lrclib data dump, local LLM and a super two step prompt that extracts extremely high quality lyric based metadata (about the narrator, protagonist, setting, story arc, moods etc)
Anyway, even though I bitched about MusicBrainz in another comment, their JSON dumps can be coaxed into giving the sort of metadata that I wanted to get from RYM, who absolutely suck due to their crazy aggressive blocking, self sabotage and unforgivable data poisoning if you trigger their bot tripwire. Their data came from their users, but as a paying user you can't use their site to tag your music. No API, and you get banned if you try to write a music player plugin to fix the tags in your "now playing" track. I don't know what their business plan is, or who they think their audience is.
The site looks nice, but I don't see an API option which makes it a non-starter for me. Having seen similar sites come and go over the years, I must assume that at some point my curated data will disappear. Or am I missing something?
No doubt the average person isn't going to be looking to integrate with your system via API, so maybe you're fine with it. Anyway, just some feedback from the fringe I suppose. Good luck with your project!
