I've tried self-hosting with navidrome [0] / plex / jellyfin but the thing I miss most is music discovery via radios / discover weekly. I've tried replicating it a few times with embedding vectors + vector search but at best it finds songs in the (sub)-genre with the tempo / mood being pretty different.

Maybe I just need better data, been meaning to try again when that spotify crawl by annas-archive gets released. I've just been using musicbrainz [1] and youtube. Model-wise I've tried off-the-shelf ones like [2] and [3] and training auto-encoders like VAEs / MAEs [4]
