Not sure if you already know this, but there is a plugin called “Tubifarry” for Lidarr, that directly integrates slskd as an indexer and download client in Lidarr. I’ve recently switched from Soularr to the plugin and it works really well. In combination with the “Search Sniper” Import List you can still get that random backfill behavior of Soularr.

Here is some general information on lidarr Plugins. You have to use a special branch/image. There’s also a link to Tubifarry at the bottom of the page.
