That said my app stablekraft.app does have some Nostr stuff added to it. Status updates for what your listening to, favorites (bookmarks) that are stored on Nostr and I use the metadata proposal that nostr:npub1unmftuzmkpdjxyj4en8r63cm34uuvjn9hnxqz3nz6fls7l5jzzfqtvd0j2 uses with Fountain when a user sends a boost and those even show up in Fountain b/c its the same spec.

Podcasting 2.0 uses GUIDs to identify items and thats how Fountain knows what song or album I'm Boosting.
