By that I mean randomly generated playlists. Based on either one or multiple tags, songs or artists. Finite or infinite.
Ideally it would allow combining local sources with remote ones for discovering new music. Thinking along the lines of audioscrobbler, Bandcamp and SoundCloud. Maybe one could even hook into Spotify’s API, of they allow that.
Does something like this exist? I’m currently running Navidrome and while it’s pretty and functional, it’s very much a classic Mediaplayer, that just happens to be a website.
It’s also primarily for self-publishing. When sharing music that’s not your own I suspect you quickly run into the same issues as with torrents. With probably similar solutions.
I’ll check out Spotube and SimpMusic, although the local music part is missing from your description.
