A Self-Hosted Playlist Mirror for Seven Music Services

How I built SongMirror, an always-on playlist mirror for Spotify, TIDAL, Qobuz, Deezer, Amazon Music, Apple Music, and YouTube Music, plus a Jellyfin-ready local archive. It supports one-way sync, authoritative provider groups, and bidirectional N-way reconciliation behind ISRC-first matching, durable caches, and guarded removals.
