Seconding this. I have an instance running on my home server, and it works great. I have a listening history going back just over a decade now, and I can see how my taste has changed over the years. It’s a neat tool.

Edit: just looked at it. Over 10 years, I have a little over 200 days worth of listening time. It has some neat graphs. And I like that I can dive deep and pick a specific song or artist and see things like “when I first listened” and my full play history for that specific song.
