Maxim, thanks a lot for the ideas. I take note. The reason for using org-web-tools is that the web page that GNUMP3d serves is extremely simple, with an alphabetical list of artists, titles, and links to the .m3u to stream. The list is easily reusable in Org. In the end I managed to write a function to create in each node a property drawer with album title, date and artist, accessing each m3u and obtaining the information with ffprobe (screenshot: https://i.imgur.com/1ALe4Ah.png).
