Open Source Music
A music collection you actually own behaves differently from a streaming catalog: nothing leaves your library because a licensing deal expired, no algorithm reshapes what you reach for, and the bitrate is whatever you ripped rather than whatever a tier allows. The open source tools here turn your own files into a streaming service you host, so the songs reach every device over your network and the catalog answers to your shelves instead of a vendor's contracts.
