Love the concept. Definitely its a interesting use case. Im working with nostr:npub149p5act9a5qm9p47elp8w8h3wpwn2d7s2xecw2ygnrxqp4wgsklq9g722q in types of nostree list, to create 'templates', so users can choose this ones and befits from specific functionalities like indexing or fetch metada form external apis.

Also i have in mind from long time ago to add functionalities to add events(nip52), or at least show them in users profiles... All this together con be quite interesting for musicians
