Hi, I'm the developer of Rune. Honestly, I was a bit surprised to see my software mentioned on HN at this time. I had planned to introduce it once it had fewer bugs, improved performance, and cleaner source code.

Nevertheless, Rune might offer the features you're looking for. It not only provides recommendations based on individual tracks but also on criteria like "songs you've liked," "all music from a specific directory," or "all tracks from a particular album." Additionally, it can categorize recommended tracks into nine sub-lists based on acoustic features, helping you find the perfect arrangement.

Thanks to its separation of front-end and back-end, Rune can be used independently of a GUI. You can also use Rune's CLI to create M3U playlists. While these features haven't been fully refined due to my limited resources, I believe Rune has the potential to meet your expectations in the future.

Here are the document of the query syntax: https://github.com/Losses/rune/blob/master/documents/mix_que...

I hope that once Rune reaches a production-ready state, you'll remember it. I'll be looking forward to that day.
