ive been trying to get cmus to add a usable URL to NIP-38 events, this is the hard part if you're playing old fashioned mp3s from a folder and not using one of the big services, i think most i could do is add a bandcamp url when known (which provides a link to a info page... getting a direct link to the stream from there is a scraping hassle)

ideally there would be some service agnostic identifier but no idea if that exists, nor would it be easy to find that 🙂
