The first thing that pops into my head is using a list to push notes of liked/zapped tracks listened to on wavlake. Posting stuff you listen to seems to be a popular thing to do, so why not set up a list to automate that?
Eventually, I'd like to have nostr keys integrated into a fork of nextcloud so that you can have a list control what nyms are allowed to access files without needing to have anyone sign in or deal with password nonsense.
Heck, if there's ever a hardware nostr signer, you could use that as a controlled access door lock.
