This whole thread shows many people don't mind spending time building their own content library and making their own little Netflix on their NAS. I think this is just the beginning.

I have been a happy user of JellyFin for a couple of years. Then when Spotify raised its prices again I realized I mostly listen to the same songs, most if not all I still own the CDs.

So with Navidrome and a couple of Python scripts to transform playlists, I made my own little home Spotify as well (Homify? Hopify?)

Works perfectly. No fees. No ads. No stupid email at the end of the year bragging about all the data Spotify collects and stores about me. Perfect.
