Another reason to host your own music, sometimes albums on Spotify are just missing a track. Like the example below from Crystal Castles. If you self-host it with Navidrome, for example, you can put whatever you want on it, whether it has been removed for legal reasons (often sample licensing) or it is unreleased. Very annoying when Spotify doesn’t even tell you that a track is missing, especially when they are such bangers.

Side note. A great feature of Navidrome, I could just download this track with the format and bitrate I want, 320kbps mp3 in this case. De server just transcodes it on the fly for smaller download sizes. I have this track in FLAC but that file is more then 30MB, way to much to post here.
