This has me dream of a Nostr based music streamer. Store your settings in an encrypted event, share favorites and playlists directly on Nostr and whatnot. And you could even bring what you already have with something like this (below) exporting to a file! Ah, randomly super random ideas for things I will probably never write but would still be interesting are my favorites. xD Pointless into-the-void dreaming.

How about shared file streaming aka Plex with Holepunch?
Interesting... Could probably do WebRTC nego via Nostr short-term events, like exchanging ICEs and then using that WebRTC to dump data over the wire.
Hmmmm...
Blossom for storage, Nostr (WOT?) for discovery, streaming similar to zapstream? Not sure but there might be an opportunity to disrupt this market.
