I'm looking for a self hosted music server (or client) that has good automatic playlist generation from a selected song, like Spotify's "your recommended". I'm currently running jellyfin and navidrome for music. The closest I've seen is beatbump but it uses YouTube for the music, I'm hoping to use my local files. Any suggestions?
Plexamp has completely replaced streaming services for me. Plex will now sonically scan any music you add and is able to give recommendations through Plexamp for sonically similar tracks, and also use that data to build mixes based on mood and style.
There are all sorts of auto generated mixes that Plexamp will make on it's own based on the music you have. You can also make a playlist of say, your top 20 tracks and when the playlist ends Plexamp will just start playing songs that match the sonic theme of what you've been playing so far. Note that I say sonically similar rather than of a similar genre. I love this because genres are often very subjective, and while Plex does take into account the tags you've given things, it also will group songs based on how they actually sound. You can control how many degrees of separation too if you want to keep the theme close to your playlist or just let it wander through your collection.
For me at least, Plexamp is every bit as good as Spotify. My music collection has grown to around 20,000 tracks over the years and it's pretty easy to get stuck on the same handful of artists. Mixes and auto playlist generation in Plexamp has helped me rediscover music I forgot I even have.
I've had issues with Plex not scanning all of my media. Not sure if it has to do with the format that lidarr stores music on disk or what. Have you had this issue?
I can't say that I have. I've never used lidarr though so if there is an issue with that I'm not the person to ask.
I find Plex to be pretty bullet proof, and I have family scattered all over the US, and one in Europe, who all use my server and we don't run into many issues. Very occasionally I'll get a message something isn't working and just restarting Plex always seems to fix it. I like self hosting but I'm not any sort of tech wizard. If it took a lot of work to maintain or had a lot of problems with multiple users I'd probably just abandon it, but I've been running it for the better part of 15 years now and it's pretty solid/dummy proof in my experience.
