RSS is a great idea, I will look more into this.
Just for info, there is already Wavlake. They accept zaps and accounts are based on NOSTR: https://wavlake.com/
The app for the phone works really good, I use it often to scrooble and find new artists.
Unfortunately Wavlake doesn't surface self-hosted RSS feeds and doesn't allow artists to implement infinite value splits since they are custodial of the artist's value. Pretty UI though. It's kinda like Spotify 2.0 so I steer clear lol BUT you can hear EVERY Wavlake artist on ANY Podcasting 2.0 app and still send them sats.... Err well of course you are sending your sats to Wavlake and trusting they give 90% plus your message to the artist...
What app would you recommend to try out then?
LNBeats.com is where I go to discover new decentralized music (DeMu) and I have it downloaded as a PWA on my phone. Podcast Guru is my main Podcasting 2.0 app, but I also use Podverse and Fountain. I recommend trying multiple from the list of Podcasting 2.0 apps: https://podcastindex.org/apps
That is really cool, didn't knew it was already working. Will bookmark it.
