I’ve wanted to replace Spotify for years but have never been able to do it. Everyone here will suggest you just use Jellyfin, but that doesnt solve the discovery problem. My idea was basically using spot-dl to download playlist and add them to my music library. But it would always break after a few days and the metadata was always all messed up.
I think its possible to do, I just gave up too soon. To get approval from my wife it has to be better than Spotify, and even if I got it to work, it just won’t ever be better so I gave up for now.
Pretty much the only way I’ll be able to replace it is if it enshittifies a lot more. Like certain record labels dropping out or something along those lines. She wants to use 1 single app for all her music and podcasts and at the moment, that can’t be done well. Spotify has to do something dumb to Nerf its value proposition.
