Hey! Sorry for the late response. Kind 36787 and 34139 are nostr specific formats. It's a decentralized way to publish music, much like podcast 2, except there's no hard dependency on domain names. That means posts with links to, say, youtube will not show up there. One way to see it in action and understand it, is by going to https://nodecast.xyz (a nostr music client) and let it fetch music notes from the relay, like in this image: Although it seems later versions of nostria.app fetch from wss://drops.basspistol.org automagically. 💜 While many relays support these kinds, not many clients do yet. That's likely why it appeared empty to you. However, we like to be ahead of the curve and want to offer a playground for musicians to store their notes in a space that people can browse with the assurance that they'll find decentralized music. Here's the list of nostr clients that support it, to our knowledge: https://grimoire.rocks https://nostria.app/music https://sunami.app/ https://nodecast.xyz https://zaptrax.app/ https://cove.band/ Hope it helps!
