Cancelled my Spotify membership a month ago and have been searching for a self hosted music alternative. Now set up a Navidrome instance on a Pikapod server. Very easy to set up (a few mins and clicks of buttons). Uploaded 2k+ songs from my archives. Cheap to run (approx $3 a month). Accessible on all my devices. So far, so good.
