Advice on selfhosted audio setup

Hello ! After Jellyfin full and super neat setup, I’m thinking of getting off YouTube Music to selfhosted music. Navidrome is installed with Lidarr (very questionable in the setup), slskd and Aurral. Nothing is definitive and I’m looking for solutions. I’d like first to get all my liked music and playlists off YouTube Music in my library. Either by downloading from YT or through any other provider. Some tracks I want are long mix and concert so for those I’ll need to get them from YouTube. Any flow to get it done automatically or half automatically ? (Like Seer : request it will download organise and put the right meta tags). And for the follow up and discovery what do you use and how to work it everyday ? Discover the. Download then organise then listen. I started downloaded all the discography of each artist in one playlist of one type of music and was overwhelmed with 850 albums… if I go to all styles I like I’ll end up with 10K albums of music I’ll not listen for most of it. Well the way YT and Spotify and Deezer works is quite fine, any advice on getting a smooth transition experience ? Or should I go through albums and just listen them as if I was back in my childhood in the 90’s ? Thanks !
