I self host Navidrome, and after deploying one or two companion apps for Navidrome, I’m right now digging Substreamer. I have never heard of Tempus, so I have added it to the ‘apps to try’ list. One of the features of Substreamer that I really enjoy is the Playlist Builder. Substreamer apparently goes through your collection and pre-creates playlists based on commonalities like genre, tags, etc. Let’s say that you click on the Blues playlist. It then has the Blues master playlist broken down into All Time, Recent, 2010+, etc. After you listen to/edit the playlist, you can save it to Navidrome. I find this feature to be quite handy and it just works very well for me. Not only can I physically make playlists in Navidrome, but in Substreamer automatically as well.

Saying all of that to say, does Tempus have any such feature? Like I said, I’ve never heard of Tempus, which really doesn’t mean much, but it looks very well put together. I’m sure OP didn’t set out to make Tempus a Substreamer copycat, I just find that one feature of Substreamer very handy.
