I haven't built anything following the podcasting 2.0 spec, so I don't know how hard/easy it is to build something to zap.

What I do know is that I spent the afternoon picking up the little crumbs of info from wavlake's blog and digging through wavman's code to figure out how to programmatically search for music on nostr and zap it. Surprisingly kinda a pain in the ass, but would have been simple if they documented the process somewhere. Would love to know how it compares to the RSS model, but it's naturally different since music is discovered via relays as opposed to subscriptions.

Overall, a pain in the ass. But I'm also not a web dev by choice (though I find myself doing it a lot lately), so take that for what you will.
