Since the music isn't posted on nostr, it will not show up om DROPS.. but the good news is, since it posted on podcast2 it's dead easy to put it on nostr. Just:
- go to https://nostria.app/music
- login
- hit the ➕ button and chose "import from rss"
Like this:
Then paste the feed url and proceed from there! From the link you posted, the feed url would be this one: https://pirate.mxtthxw.art/@inpc/feed.xml
Just ping if you're struggling!
