I've gotten spoiled by Spotify's ability to find music that I had no idea I would want to listen to until I hear it. I want to move back to a self-hosted model for my music needs, but everything I see right now requires me to know what I want to hear and download it before hand.

Is there any sort of selfhosted software anyone knows of that'll maybe analyze my library and recent songs and generate playlists, connect to Lidarr and instruct it to download the songs?
