Nice, if we understand correctly on v4vmusic it's done through tags which are stored in v4vmusic itself. And anyone can edit those tags, @Sir Libre you can confirm but it can be destructive cause we just updated tags for a couple of songs and nothing stopped us.

Difference with NIP-32 tags that they live on Nostr (not on our infrastructure) so they are available for anyone. Also we support counter tags to mark things as people content in case someone maliciously or mistakenly tags tracks.

It means that any music client can support ai tags just by quering Nostr!
