Macos Sources

Hi, your project is really great, but the fact that it only supports apple music and spotify as sources on macos is a bit limiting. Do you plan to add other sources, like browser based ones, in the future?

I saw a project for media playback on macos, maybe that could help.

Begin by examining the existing Apple Music and Spotify source implementations in the Rust project and the linked media-remote project. The issue does not identify a target browser source, files, tests, or acceptance criteria; it is complete only after a specific source and supported behavior are agreed and verified.
