Thanks for putting this together! This is an excellent write up and is super informative! I'm already using Navidrome + Tempo with Lidarr for my music library, but since the database issues with Lidarr popped up a few months ago I haven't bothered adding new stuff.
I had no idea Explo was a thing, it's just what I've been hoping existed. I'm going to try and get it integrated into my set up.
